  • Fabry-Perot type tunable filter and fabrication method thereof
    Patent number: 8164757
    Abstract: To provide a miniaturized Fabry-Perot type tunable filter that can be applied to e.g. a light of wide wavelength range from infrared rays to ultraviolet rays and actuated at a low voltage. A movable portion moving in a direction parallel to the surface of the SOI substrate (hereafter called ‘plane direction’), a suspension supporting member supporting the movable portion elastically and movably, and a fixed portion secured to the SOI substrate are provided. By the comb-teeth electrode of the comb-teeth type electrostatic actuator that moves the movable portion, the first mirror structure body formed bonding to the surface of the movable portion is controlled and moved in the plane direction.
