    Abstract: PROBLEM TO BE SOLVED: To prevent a light signal from entering a destination fiber by going over a gap by mechanically connecting an actuator and a reflector, and changing a light-actuated photon switch state by moving the reflector by actuation of the actuator. SOLUTION: When a photogenerator 104 is irradiated by a light beam 112 through an optical fiber 110, the generator 104 generates voltage, and the voltage is transmitted to an actuator 126 of a microscopic electronic machine system MEMS structure 124 through electric conductors 106 and 108. When the voltage is transmitted, a reflector 130 capable of changing a light signal characteristic by reflection, diffraction, absorption and the others, moves to a passage of a signal 134 from a signal source fiber 132a by a connecting mechanism 128. Therefore, the light signal 134 can be prevented from reaching a destination fiber 132E by going over a gap 136. Here, the dimension of the gap 136 can be comparatively reduced to about 20 μm without a lens, and becomes fairly large with a lens.

    Abstract: PROBLEM TO BE SOLVED: To provide adaptive optics in the type of a micromachined mirror to eliminate the optical/mechanical independence of a uniform reflection layer and to eliminate the many actuators of the conventional mirror arrays. SOLUTION: This article for directing a light signal between optical waveguides is disclosed. The article includes plural mirror elements which are mechanically and electrically interconnected and form reflection surfaces. The reflection surfaces can be deformed by impression of voltage. The light signal sent from the source waveguide can be directed to the different destination waveguides when the reflection surfaces are deformed. The plural mirror elements are actuated by the single actuator.

    Abstract: PROBLEM TO BE SOLVED: To provide a variable optical delay line using a MEMS device. SOLUTION: A reflecting machine on a micromachine linear rack is disposed separating from an input source and/or the output point, an input light wave signal is received and is directed to the output point. The distances between the reflective machine and an input point and between the reflecting machine and the output point are variable, and, thereby, the selective pass delay compensation of a input light wave signal can be performed. The selective pass delay compensation necessary for an optical system is given by adjusting the pivot angle between a pivotally drivable MEMS mirror and a pivotally drivable mirror in another embodiment.

    Abstract: PROBLEM TO BE SOLVED: To provide a micro-fabricated optical switch with tapered end parts. SOLUTION: An optical switch 100 comprises four optical waveguides 130, 140, 150, 160 with tapered end parts, and the end parts each have two tapered parts and are arranged on a support, by which each tapered end of each waveguide is faced proximately to another tapered part and a space is specified between each pair of the facing tapered ends. A 1st electro-mechanical driver 108 is contained, which is capable of operating so as to move a 1st optical device 102 at least in and out of an optical path of an optical signal propagating between two waveguides, and the 1st optical device is moved in the space between a 1st pair of the facing tapered ends, and a 2nd optical device 118 is contained, which is capable of operating at least so as to move a 2nd optical device 112 in and out of an optical path of an optical signal, and one tapered end of the 1st pair and one tapered end of the 2nd pair are common to one of the optical waveguides.
