    Abstract: The present invention discloses a manufacturing method of an integrated structure of a MEMS microphone and a pressure sensor, which comprises the following steps: depositing an insulating layer, a first polycrystalline silicon layer, a sacrificial layer and a second polycrystalline silicon layer in sequence on a shared substrate; etching the second polycrystalline silicon layer to form a vibrating diaphragm and an upper electrode; eroding the sacrificial layer to form a containing cavity of a microphone and a pressure sensor, and etching the sacrificial layer between the microphone and the pressure sensor; etching the first polycrystalline silicon layer to form a back electrode of the microphone and a lower electrode of the pressure sensor; etching a position of the shared substrate below a back electrode of the microphone to form a back cavity; and etching away the region of the insulating layer below the back electrode. A capacitance structure of a MEMS microphone and that of a pressure sensor are integrated on a shared substrate, improving integration of a MEMS microphone and a pressure sensor, and greatly reducing a size of a whole packaging structure; in addition, a microphone and a pressure sensor can be simultaneously manufactured on a shared substrate to improve the efficiency of production.

    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.
