Embodiment 1

[0062] In view of the shortcomings of current DGE and DGSE device technologies such as high cost, large insertion loss, high drive power consumption, and large volume, this invention proposes a technical solution for a dynamic gain slope equalizer based on MEMS technology, using a MEMS two-degree-of-freedom micro-displacement driver, A free-space optical MZI with independent tunable optical splitting ratio and optical phase, featuring low insertion loss, large spectral slope equalization range, fast tuning, low drive power consumption, low cost, and small size, and can be directly integrated with GFF Into EDFA, thereby solves the problem of EDFA dynamic gain equalization. At the same time, it can also be applied to solve the problem of signal power imbalance between DWDM channels caused by transmission optical fiber, optical fiber dispersion compensation module, optical fiber stimulated Raman scattering (SRS) effect, etc.
