Abstract: A wavelength tunable gain medium with the use of micro-electromechanical system (MEMS) based Fabry-Perot (FP) filter cavity tuning is provided as a tunable laser. The system comprises a laser cavity and a filter cavity for wavelength selection. The laser cavity consists of a gain medium such as a Semiconductor Optical Amplifier (SOA), two collimating lenses and an end reflector. The MEMS-FP filter cavity comprises a fixed reflector and a moveable reflector, controllable by electrostatic force. By moving the MEMS reflector, the wavelength can be tuned by changing the FP filter cavity length. The MEMS FP filter cavity displacement can be tuned discretely with a step voltage, or continuously by using a continuous driving voltage. The driving frequency for continuous tuning can be a resonance frequency or any other frequency of the MEMS structure, and the tuning range can cover different tuning ranges such as 30 nm, 40 nm, and more than 100 nm.

Abstract translation: 提供使用基于微机电系统（MEMS）的法布里 - 珀罗（FP）滤波器空腔调谐的波长可调增益介质作为可调激光器。 该系统包括用于波长选择的激光腔和滤光腔。 激光腔由诸如半导体光放大器（SOA），两个准直透镜和端反射器的增益介质组成。 MEMS-FP滤光器腔包括固定反射器和可由静电力控制的可移动反射器。 通过移动MEMS反射器，可以通过改变FP滤光器腔长度来调节波长。 MEMS FP滤波器腔位移可以用阶跃电压离散地调节，或者通过使用连续的驱动电压连续地调节。 连续调谐的驱动频率可以是谐振频率或MEMS结构的任何其他频率，调谐范围可以覆盖30nm，40nm和大于100nm的不同调谐范围。
