All-Optical Ultra compact Photonic Crystal Switch Based on Nonlinear Micro Ring Resonators

ABSTRACT: In this paper an all-optical switch has been proposed based on photonic crystal T-type ring resonator. The finite different time domain (FDTD) and plane wave extended (PWE) methods are used to analyze the behavior of the structure. The T-type ring resonator has a low switching time of about 0.95ps and low switching power equal to 156mW/µm2. Since the structure has a simple geometric shape with clear operating principle, it is potentially applicable for photonic integrated circuits.
