Tilted Fiber Bragg Grating are optical fiber type devices that form diffraction gratings in the core of an optical fiber and function as an optical filter. The FBG can select the light transmitted through the optical fiber core, and by separating the transmitted light from the reflected light, the FBG serves as an optical filter. We uses a proprietary optical system to write the FBG into the optical fiber core, enabling a wide range of wavelengths to be selected and stable production. Since we can manufacture products in a wide variety of wavelengths, we can accommodate individual specifications from a single prototype, so please consult with us.
