    摘要： An optical switch, wherein the first and second output ports (optical fibers) are disposed on the opposite sides of the input port (optical fiber) so as to form acute angles with respect to the input port, the input port and the first output port are optically coupled to each other through a first mirror surface, and the input port and the second output port are optically coupled to each other through a second mirror surface. The incident angles of an incident light beam with respect to the mirror surfaces are equalized, and optical path lengths between the input port and the first and second output ports are equalized. The actuator inserts and withdraws the second mirror surface on a position at the front of the first mirror surface.

    摘要： A micro-optic device including a complicate structure and a movable mirror is made to be manufactured in a reduced length of time. A silicon substrate and a single crystal silicon device layer with an intermediate layer of silicon dioxide interposed therebetween defines a substrate on which a layer of mask material is formed and is patterned to form a mask having the same pattern as the configuration of the intended optical device as viewed in plan view. A surface which is to be constructed as a mirror surface is chosen to be in a plane of the silicon crystal. Using the mask, the device layer is vertically etched by a reactive ion dry etching until the intermediate layer is exposed. Subsequently, using KOH solution, a wet etching which is anisotropic to the crystallographic orientation is performed with an etching rate which is on the order of 0.1 μm/min for a time interval on the order of ten minutes is performed to convert the sidewall surface of the mirror into a smooth crystallographic surface. Subsequently, the intermediate layer is selectively subject to a wet etching to remove the intermediate layer only in an area located below the movable part of the optical device.

    摘要： Marker grooves of an optical fiber are formed by a marker groove forming device including at least, on a substrate, a fiber guide and optical fiber pressing springs formed on a side wall surface in the fiber guide. The optical fiber pressing springs include edges contacted and pressed to the side of an optical fiber stored in the fiber guide, and plate springs for pressing the edges to the side of the optical fiber with fulcra on the side wall surface in the fiber guide. The optical fiber is pressed to a side wall surface in the fiber guide, and the edges are formed at a predetermined distance from each other.

    摘要： A miniature movable device comprises a movable part (a mirror, a movable rod, support arms, and a movable comb tooth electrode) formed on a substrate and adapted to be displaced in a direction parallel to the sheet surface of the substrate, a fixing part formed and fixedly mounted on the substrate, and hinges, each having its opposite ends connected to the movable part and the fixing part and assuming two flexural conditions which are reversed in flexural, the hinges being effective to maintain the movable part at two positions by a self-holding action when it assumes either flexural condition. The substrate is formed with wall surfaces which are disposed oppositely to the opposite surfaces of the hinges over a movable range of the hinges. Spacings between the hinges and the wall surfaces disposed on the opposite sides thereof are equal to each other at every point along the lengthwise direction of the hinges when the hinges assume one of the two flexural conditions (an initial condition assumed upon manufacture). This eliminates an inconvenience that during a drying step which follows a wet etching operation during the manufacture, a liquid may remain on only one side of the hinges to cause the hinges to be held attracted to the wall surfaces.
