1550nm desktop broadband tunable filter (range 80nm FWHM bandwidth 1nm Gaussian shape)

The voltage controlled tunable filter independently developed by Xiaoxiao is based on free space optics and combined with MEMS filtering technology to generate Gaussian shaped transmission. It is a 2-port fiber optic device. Optical design provides a good choice for bandwidth and tuning range, with low insertion loss and polarization related loss (PDL) that are not available in the market. The precise tuning mechanism enables the filter to provide high wavelength resolution and excellent wavelength tuning repeatability. At present, this filter can be used for X O. S, C, and L bands
