摘要：Problem to be solved: to reduce electrical wiring in an optical signal processingapparatus such as an optical switch or an optical filter realized using an opticalwaveguide. An optical signal processor having an optical waveguide formed on a

substrate;The optical waveguide comprises at least one input portHaving at least oneoutput portThere are a plurality of driven elements including phase shifters to providephase shift to the optical signal input from the input portEach driven element has at leasttwo control terminalsA control wiring for applying a time-division synchronous controlsignal between the two control terminals is provided.An optical signal processingapparatus in which the control wiring to be accessed to the driven element is shared by aplurality of driven elements is used.Diagram
