A new compact delay structure based on two-dimensional photonic crystal (PC) is presented. The delay structure consists of a PC waveguide loop and a PC coupler switch. The optical signal pulse is delayed when it circulates in the waveguide loop, and the delay process is controlled by the coupler swi
