[0041] In the following, the present invention will be further explained through embodiments with reference to the drawings.
[0042] In this embodiment, the MEMS-based multi-channel tunable fiber laser of the present invention includes three fiber optical modules and one bulk optical module. Each of the three fiber optic modules includes a fiber amplifier 1, a fiber coupler 2, an fiber 3, and a double pigtail collimator. The three double pigtail collimators form a double pigtail collimator array 4; a bulk optical module It includes a first lens 5, a grating 6, a second lens 7 and a MEMS processor 8. The MEMS processor is a very large-scale integrated circuit equipped with a MEMS chip. The MEMS chip is integrated with a pixel array and collimated with three double pigtails. The device is divided into three working areas correspondingly, such as figure 1 Shown.
[0043] Among them, the components in the three fiber optic modules all use polarization-maintaining components, namely: ...
