    摘要: Provided is a wavelength tunable optical filter of a micro-electro-mechanical system (MEMS). The wavelength tunable optical filter comprises two optical fibers or optical waveguides having their optical axes aligned to each other, two lens for collimating light at leading ends of the optical fibers or optical waveguides, two or more mirrors formed on a substrate, thermal actuators supporting at least one of the mirrors, wherein one of the mirrors is actuated by thermal expansion of the actuator. Because all mirrors are formed on a substrate, a manufacturing process is simple and an initial resonance wavelength can be precisely adjusted. Since the thermal expansion is generated by the electrical current directly flowing through the thermal actuators, it can be actuated by a low consumption power. Also, since an electrostatic force is not used to move the mirrors, a sticking phenomenon between the mirrors does not occur, and the wavelength can be tunable in a wide range. Since the planar mirrors are arranged in parallel, the light alignment is easily performed, the line width is constant and the insertion loss is low.

    摘要: Provided is a high-sensitivity MEMS-type z-axis vibration sensor, which may sense z-axis vibration by differentially shifting an electric capacitance between a doped upper silicon layer and an upper electrode from positive to negative or vice versa when center mass of a doped polysilicon layer is moved due to z-axis vibration. Particularly, since a part of the doped upper silicon layer is additionally connected to the center mass of the doped polysilicon layer, and thus an error made by the center mass of the doped polysilicon layer is minimized, it may sensitively respond to weak vibration of low frequency such as seismic waves. Accordingly, since the high-sensitivity MEMS-type z-axis vibration sensor sensitively responds to a small amount of vibration in a low frequency band, it can be applied to a seismograph sensing seismic waves of low frequency which have a very small amount of vibration and a low vibration speed. Moreover, since the high-sensitivity MEMS-type z-axis vibration sensor has a higher vibration sensibility than MEMS-type z-axis vibration sensor of the same size, it can be useful in electronic devices which are gradually decreasing in size.
