摘要： A wavelength tunable filter capable of being driven such that reflecting mirrors move more distant as well as closer by using the principle that a direction of the electromagnetic forces changes depending on the direction of the current flowing perpendicular to the external magnetic field. According to the wavelength tunable filter of the present invention, when it is necessary to have the wavelength tuning range and mechanical structure similar to the conventional wavelength tunable filter driven in only one direction, it is possible to lower the maximum force needed to drive the filter to a half, and reduce a probability that a pull-in phenomenon occurs. On the other hand, it is possible to reduce a wavelength change time of the element by increasing a resonant frequency when the same wavelength tuning ranges are implemented by using the same maximum driving forces.

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.
