Advanced VCSEL Laser Diode Technology and Diverse Applications

Vertical-Cavity Surface-Emitting Lasers (VCSELs), a core semiconductor laser technology, are pivotal enablers for cutting-edge fields like AI and IoT, valued for their unique structural advantages and broad applicability. Backed by deep technical expertise, our VCSEL portfolio covers multi-wavelength and multi-power solutions, serving industrial, medical, and consumer electronics sectors.

Our VCSEL technology centers on GaAs-based epitaxial design, leveraging proprietary optical design software and process know-how to meet multi-dimensional requirements. Customizable epitaxial structures and device parameters (e.g., ±10nm wavelength control via DBR thickness adjustment) address stringent spectral matching requirements. Key processes—ICP etching (nanometer precision), wet oxidation (optimizing beam divergence to 10°), and BCB planarization—ensure optical stability and mode control.

(1) Full-Waveband Coverage and Power Flexibility

• Visible Light: Blue/green/orange modules (500mW+ power, near-diffraction-limited beam quality) enable laser display and bio-fluorescence applications. Example: 650nm red modules (linewidth <100MHz) for stage lighting and medical aesthetics.

• Near-Infrared Portfolio:

• Low-Power Precision: 790nm single-mode VCSELs (SSK-790 series) deliver 1.2–1.5mW at 3.5mA, with ±0.06nm/°C wavelength stability via TEC control, ideal for atomic clocks and magnetometers.

• Industrial-Grade High Power: 808nm VCSEL arrays (100W peak, microchannel water cooling) enable 12mm metal cutting in QCW mode.

• Ultra-High Pulse Power: 940nm double-junction VCSELs (400W peak, nanosecond pulses) support LiDAR with adjustable 60°×45°–120°×90° beam angles.

(2) High-Precision Integration and Environmental Robustness

• Smart Thermal Control: TO46/TO56 packages integrate TEC (70°C max delta, 0.4W cooling) and NTC sensors for ±0.1°C temperature stability, ensuring <5% power drift in high-temperature industrial settings.

• Anti-Interference Design: Surface grating achieves 25dB polarization extinction; automotive-grade 850nm VCSELs (AEC-Q102 certified) withstand ±8kV ESD via EMI shielding.

• Longevity Design: 50,000+ hour lifespan, <3% power degradation after 1,000-hour CW aging tests, suited for 24/7 industrial operations.

(3) Modular Design and Customization

• 300+ Standard SKUs: 20+ packages (e.g., 2.0×1.6mm 2016AIN for compact devices, 7060CuAg with integrated heat sinks).

• Custom Solutions: Aerospace-qualified 1064nm modules (-40°C to 125°C stability) and medical 940nm annular beam modules with 360° uniform illumination.

II. Application Scenarios

1.Intelligent Sensing and LiDAR: 850nm/940nm modules for 3D ToF (smart vacuum cleaners, AR/VR) and 808nm 150W pulsed VCSELs for automotive LiDAR.

2.Industrial and Medical: 808nm CW modules (300W) for metal processing; 660nm red light for dermatology, 940nm IR for non-contact thermometry.

3.Consumer Electronics: 850nm line arrays (130mW) for 3D facial recognition; 6G/10G VCSELs for data center optical interconnects.

4.Scientific Research and Measurement: 790nm single-mode VCSELs (70MHz linewidth) for atomic sensing in high-temperature environments (up to 90°C chip temp).

III. Industry Advantages

• One-Stop Customization: From epitaxy to packaging, with conduction/water-cooled QCW modules for extreme environments.

• Certifications: ISO9001, IATF16949, AEC-Q102 certified for automotive and industrial use.

IV. Future Directions

R&D focuses on visible-light VCSELs (500mW+ green modules) and single-mode long-wavelength VCSELs (1060nm+), targeting autonomous driving and biomedical imaging.
