摘要： A grating optical switch has at least one switch region for ON-OFF switch control of a signal light transmission and a signal light reflection, at least one input/output optical waveguide region for guiding the signal light to the switch, at least one coupler region for coupling the control light colinearly to the signal light and for guiding the control light to the switch region together with the signal light, and at least one separator region for separating the signal light and the control light. The switch region transmits the signal light when the control light is coupled while reflecting the signal light when the control light is not coupled.
