Keywords: Spatial Light Modulator, SLM, light modulation, phase modulation,
A Spatial Light Modulator (SLM) is an electrically programmable device that modulates light according to a fixed spatial (pixel) pattern. SLM are typically used to control incident light in amplitude, phase, or the combination of both.
A Spatial Light Modulator (SLM) is an electrically programmable device that modulates light according to a fixed spatial (pixel) pattern. SLMs have an expanding role in several optical areas where light control on a pixel-by-pixel basis is critical for optimum system performance. SLMs are typically used to control incident light in amplitude, phase, or the combination of both.
Several parameters help define SLM characteristics. Pixel pitch is defined as the center-to-center spacing between adjacent pixels. Interpixel gap describes the edge-to-edge spacing between adjacent pixels.
Polarized light enters the device from the top, passes through the cover glass, transparent electrode and liquid crystal layer, is reflected off the aluminum pixel electrodes, and returns on the same path. Drive signals travel through the pins on the bottom of the pin-grid array package, through the bond wires, and into the silicon die circuitry. The voltage induced on each electrode (pixel) produces an electric field between that electrode and the transparent electrode on the cover glass. This field produces a change in the optical properties of the LC layer. Because each pixel is independently controlled, a phase pattern may be generated by loading different voltages onto each pixel.
High Voltage Backplanes = Fastest Response Times
Our SLMs use custom backplanes, and proprietary drive schemes to achieve response times down to 1 ms (wavelength dependent). Most other liquid crystal spatial light modulators utilize display backplanes built with standard Nematic liquid crystal, limiting response time to >30 ms.
Highest Phase Stability Commercially Available –Our backplanes are custom designed to allow high refresh rates (up to 6 kHz), and direct analog drive schemes. Refreshing the voltage at the pixel at rates far surpassing the response time of the liquid crystal ensures high temporal phase stability. Further, use of direct analog drive schemes, as opposed to digital dithering, reduces optical flicker as low as 0.1% (0.001 π radians). Low Inter-pixel Cross Talk - Our backplanes are custom designed to offer high voltage at the pixel (5 – 12 V), and a large pixel pitch. Further, our SLMs are built with Meadowlark Optics proprietary liquid crystal which minimizes the required thickness of the LC layer in the SLM. By maximizing the ratio of pixel pitch to LC thickness we are able to offer SLMs with minimal inter-pixel effects.
Broad Wavelength Capabilities - We are the only SLM supplier capable of offering SLMs designed for use from UV (>365 nm) up to the LWIR (8 - 12 µm). Analog is Better - All the SLMs have been designed for phase modulation. Unlike many display LCoS backplanes which require a pulse width modulation (PWM) scheme, our backplanes utilize analog voltages at each pixel. This results in a very stable phase response over time.
High Bit Depth Controllers - we offer 8, 12, and 16-bit controllers to provide the most linear resolvable phase levels commercially available (up to 500). Fast transfer speeds from the computer to the SLM are offered up to 2 kHz.
Polarized light enters the device from the top, passes through the cover glass, transparent electrode and liquid crystal layer, is reflected off the aluminum pixel electrodes, and returns on the same path. Drive signals travel through. There are 2 types of special light modulators: reflective analog SLMs and transmissive SLMs.
Reflective Analog SLMs: All of our liquid crystal on silicon (LCoS) backplanes incorporate analog data addressing with high refresh rates to provide the lowest phase ripple SLMs available. User’s can select standard or high speed liquid crystal for optimal performance. Liquid cooling systems are available to remove heat via the back of the SLM chip in order to maximize optical power handling capabilities:
Transmissive SLMs: All of our liquid crystal on glass (LCoG) SLMs enable simple optical systems when low pixel counts are sufficient. Users can select single-mask or configurations for phase or amplitude modulation, or a dual-mask configuration for combined phase and amplitude modulation.
High Speed Analog –up to 1 kHz
Our Liquid Crystal on Silicon (LCoS) Spatial Light Modulators (SLMs) are uniquely designed for pure phase applications and incorporate analog data addressing with high refresh rates. This combination provides users with the fastest response times with high phase stability. The 1024 x 1024 SLM is good for applications requiring high speed, high diffraction efficiency, low phase ripple and high-power lasers.
High Speed with High Phase Stability -Great care was taken in the design of the 1024 x 1024 silicon backplane to enable high speed operation while simultaneously maximizing phase stability. Engineers successfully achieved high speed without compromising phase stability.
The 1024 x 1024 SLM is incredibly fast with liquid crystal response times ranging from 0.9 to 8 ms (wavelength dependent) for a full wave of modulation when running in typical room temperature environments.

Diffraction Efficiency (0th-order)
This is the amount of light measured in the 0th-order (dc) when the SLM is written with various solid gray levels as a percentage of the amount of light measured when the SLM is replaced with a reference mirror. Therefore, it takes into account losses in transmission through the coatings on the SLM cover window, as well as diffraction losses due to the pixel pads being less than 100% fill-factor. In addition to these losses, this measurement also accounts for losses due to imperfect reflectivity of the aluminum pixel mirrors, or in the case of a dielectric mirror coated model the measurement accounts for losses due to imperfect reflectivity of this dielectric mirror coating. The 0th-order diffraction efficiency will vary as a function of wavelength due to differences in coating materials and designs. It will also vary with pixel value due to the inherent change in the index of refraction of the liquid crystal that results in a change in the Fresnel reflections inside the liquid crystal cell. Most standard SLMs will range from 70 –90%, while the dielectric mirror coated models will range from 92 –98%.
High Efficiency Dielectric Mirror Coating
All the light reflecting off the SLM is modulated –including the light between the aluminum pixel electrodes. The reflective pixel structure associated with a LCoS SLM backplane acts as an amplitude grating diffracts some light into higher orders. Optically, the active area of the backplane is converted into a flat dielectric mirror by depositing dielectric layers to eliminate the amplitude and optical path variations associated with the underlying aluminum pixel structure. The dielectric stack is kept thin to minimize any drop in electric field across the LC layer as shown in the figure below. In other words, there are no abrupt changes in phase modulation (such as dead zones) between pixels due to the smoothing which results from separating the LC modulator from the driving electrodes.
Diffraction Efficiency (1st-order)
This is the percentage of light measured in the 1st-order when writing a linear repeating phase ramp to the SLM as compared to the light in the 0thorder when no pattern is written to the SLM. 1st-order diffraction efficiency varies as a function of the number of phase levels, or pixels, in the phase ramp. Example measurement data taken at various wavelengths is shown below for phase ramps with 2 to 8 phase levels between 0 and 2π.
High Phase Stability –Making an LCOS SLM faster usually means the phase stability becomes worse. However, we’ve combined our traditional analog drive scheme with some new proprietary technologies to suppress phase instabilities to an unprecedented 0.05 –1.0% without compromising the speed. If your application requires extremely low phase ripple, please contact our engineer for more information on the 19x12 SLM. Phase ripple is quantified by measuring the variation in intensity of the 1storder diffracted spot as compared to the mean intensity while writing a blazed phase grating to the SLM. Since phase stability varies as a function of pixel voltage, this measurement approach is an average and does not represent all scenarios.
Software -Our SLMs are supplied with a graphical user interface and software development kits that support LabVIEW, Matlab, Python, and C++. The software allows the user to generate images, to correct aberrations, to calibrate the global and/or regional optical response over ‘n’ waves of modulation, to sequence at a user defined frame rate, and to monitor the SLM temperature.
Global or Regional Calibrations -Regional calibrations provide the highest spatial phase fidelity commercially available by regionally characterizing the phase response to voltage and calibrating on a pixel-by-pixel basis.

We are mainly engaged in the application technology research and development of digital micromirror spatial light modulator (Digital Micromirror Device-DMD). It is a high-tech enterprise specializing in the research and development, production and sales of hardware and software in digital light process (DLP) related fields such as semiconductor maskless lithography, computational imaging, compressed sensing and 3D detection. Our products include SFG-F3010, SFG-F4100, SFG-F4200, SFG-F4500, SFG-F4710, SFG-F4320, SFG-F6500, F SFG-9000, etc., widely used in scientific research, 3D scanning and LDI industries.
The company has been composed of young and middle-aged technical backbone R & D team, can be said to provide customers with DLP scheme design, DMD drive control system design and other services. At the heart of the digital micromirror spatial light modulator is the digital Micromirror device (DMD), an optical semiconductor module and a MEMS chip in which each lens can be deflected ±10deg, ±12deg or ±17deg respectively, around the hinged shaft. The DMD chip mainly regulates the rotation Angle of each micromirror on the chip according to different digital signals transmitted by the front-end circuit to the CMOS chip, so that the light irradiated on the micromirror can be selectively reflected to the imaging surface for imaging. Since the deflection of the lens is controlled separately by the underlying CMOS control circuit and the binary information of the reset signal of the lens, the optical field digital flower modulation can be realized. Because DMD is reflected by aluminized micromirror, almost no energy absorption, and controlled by CMOS technology, the speed, accuracy, energy and efficiency of light modulation are far more than other spatial light modulators.

At heart of the Digital Micromirror spatial light modulator is the Digital Micromirror device (DMD), an optical semiconductor module and a MEMS chip in which each lens can be deflected ±10°, ±12°, or ±17.5°, respectively, around the articulated shaft. The DMD chip mainly regulates the rotation Angle of each micro mirror on the chip according to different digital signals transmitted by the front-end circuit of the CMOS chip, so that the light shin on the micro mirror can be selectively reflected on the imaging surface for imaging. Since the deflection of the lens is controlled solely by the underlying CMOS control circuit and the binary information of the lens reset signal, the digital modulation of the optical field can be realized. Because DMD is reflected by aluminized micro mirror, almost no energy absorption , and controlled by CMOS technology, the speed, accuracy, energy and efficiency of light modulation is far higher than other space light modulators. DMD technology is widely used, including spectral analysis, maskless lithography, 3D measurement, naked eye 3D display, holographic imaging, compressed sensing, biological microscopy, SLA 3D printing, machine vision, etc.
