OPTICAL INTEGRATED CIRCUIT

摘要

PURPOSE:To attain high speed operation by driving a switching means by a driving means on the basis of a control signal detected by a control signal detecting means and supplying power necessary for said operation from an accumulating means accumulating power from an optical power genertaing means. CONSTITUTION:A control signal switching light is inputted to the control signal detecting means 23 consisting of a photodiode through an optical fiber 25. The detected control signal is amplified by the driving means 24. Power for these circuits is supplied from the accumulating means 22 consisting of a capacitor or the like by converting light projected from a power supplying optical fiber 26 into power by the optical power generating means 21 consisting of a photocell or the like and accumulating power in the means 22. Output voltage from the driving means 24 is apllied to an electrode 7 of an optical changeover switch consisting of a substrate 1, an optical waveguide 2, a branch 3, optical fibers 4-6 and the electrode 7, so that the optical switch operates at a high speed.
