100G bandwidth 1545-1555nm 10nm tunable filter (3dB bandwidth 0.8nm)

The core component of the filter is an optical fiber Bragg grating (FBG) with a periodic variation in refractive index. When a broadband light beam is passed through the fiber Bragg grating, each small section of the fiber with the altered refractive index reflects only a specific wavelength of light, called the Bragg wavelength, while other wavelengths of light pass through. The change in strain simultaneously affects the effective refractive index of the fiber Bragg grating and the grating period, allowing for tuning of the reflected wavelength. In this device, the Bragg wavelength can be tuned to the desired wavelength by simply adjusting the grating with a fine-threaded screw.
