COMPACT NETWORK OF OPTICAL SWITCH DEVICE

摘要

PURPOSE: To provide the compact network of an optical switch device obtained by improving the compact network of an optical shutter. CONSTITUTION: An optical switch is provided with a microshutter 5. The microshutter is arranged so that an optical path(X-X) can be interrupted or formed. The microshutter is provided with a reflection surface 7 which deflects a light when it is present at a position where the optical path is interrupted. An auxiliary reflection surface 8, diaphragm 6, and condensing lens 4 are arranged at each optical path(X-X). The microshutter deflects the light for allowing the light to pass, or interrupting the light. The light is allowed to pass by focusing the light on the diaphragm 6.
