Fiber-pigtail tunable optical filters are built based on free-space Fourier transform combing with diffraction gratings. They provide wavelength filtering such as bandpass, notch, long-pass/short-pass, and bandwidth-adjustable tunable filters covering the 1000–1700
nm wavelength band. Tuning range is up to 200 nm and the bandwidth range is 0.1–40 nm.
