Abstract

In this paper, we report an inverse strategy to design a directional emitter and power splitter based on two-dimensional photonic crystal waveguides (PCWs). Our approach is illustrated by employing a genetic algorithm in conjunction with the finite-difference time domain (FDTD) method to design a corrugated surface added behind the termination of PCWs. By arranging symmetrical or asymmetrical surface corrugations along the axis of a waveguide, we have successfully realized both a highly efficient directional emitter and an open-type Y-shaped power splitter from planar PCWs. Moreover, the angle of directional emission and split beams can be easily controlled by changing the location of the detector in the output area.
