Abstract

PURPOSE: To enable the change of the length of longitudinally coupled light delay line equivalently in order to change the delay time by coupling the lgith delay line having a fixed delay time to an optical path change circuit in a multi-step and longitudinal manner in order to control the light change circuit.
