1060-1600nm bandwidth tunable filter (flat top electric)

The bandwidth tunable filter (BWTF series) of Xiaoxiao Photon is built on a platform that combines free space optics with diffraction gratings to generate flat top transmission.

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

The core component of a filter is a fiber Bragg grating with a periodic change in refractive index. When a broad-spectrum beam of light is propagated to a fiber Bragg grating, each small section of the fiber after the refractive index is changed will only reflect a specific wavelength of light, which is called the Bragg wavelength, while other wavelengths of light will be propagated. The change in strain will simultaneously affect the effective refractive index and grating period of the fiber Bragg grating, thus changing the wavelength of the reflected light wave from the grating. In this device, the Bragg wavelength can be tuned by simply stretching the grating with a fine threaded screw to achieve wavelength tuning.
