A fibre grating is a region of fibre whose refractive index has been permanently modified by exposing to light. Such exposure, if carried out with an interferometer or phase mask, allows a periodically varying refractive index grating or pattern to be “written” into the core of optical fibre. These “in-fibre” components are spectrally selective, which allow only specific wavelengths to be reflected or rejected, and are thus suitable for performing many tasks such as filtering and reflecting, in a highly efficient, low loss manner.
We have the capability to fabricate Fibre Bragg Gratings (FBGs) and Long-Period Gratings (LPGs). An in-house designed Fibre Grating Fabrication System with sophisticated software for fabrication process control has been setup, allowing various types of fibre gratings to be fabricated including complex grating structures such as Moiré, sampled, chirped and phase shift gratings. For the first time, we have also demonstrated the possibility of directly writing gratings on an optical fibre coated with standard off-the-shelf coating, with the resulting reflectivity and index change found to be equivalent to that of a fibre grating fabricated with bare fibre.
Our FBG system can make gratings with typical characteristics:
