Abstract: Micromirror in a cross-connect switch for an optical communication system, and method for fabricating the same, the micromirror including a rotatable mirror rotatable in an X-axis direction for reflecting an incident light at a predetermined angle, rotatable beams around the rotatable mirror each connected to the rotatable mirror for rotating in a Y-axis direction together with the rotatable mirror, supporting posts around the rotatable beams each connected to the rotatable beam for supporting the rotatable beams, and a driving part on a bottom of the rotatable mirror for rotating the rotatable mirror and/or the rotatable beams as a voltage is provided thereto.

Abstract: The present invention relates to an N×N OXC (optical cross-connect) optical switch of micro-mirrors, wherein an input optical fiber bundle is fitted to a first substrate of silicon or glass, and an output optical fiber is fitted to the first substrate at a distance from the input optical fiber bundle, to face each other. There are an input micro-mirror and an output micro-mirror part between the optical fiber input part and the optical fiber output part, at a distance from the input micro-mirror part to face each other, and at 45° to a direction of an optical path of a light from the input optical fiber bundle. For fixing them, the present invention employs a method, in which grooves are formed in the first substrate, in which the third substrates of the input/output micro-mirrors and the second substrates of the input/output optical fiber bundles are inserted.
