Abstract :
We report on the design and simulation of a Y-branch formed in a two-dimensional photonic crystal patterned into a semiconductor membrane. Low-loss broadband transmission is obtained by including a resonance in the vicinity of the junction. The structure was designed using a numerical optimization algorithm that we have incorporated into our FDTD algorithm.
