All-optical Switching Structure Using Nonlinear Photonic Crystal Directional Coupler

摘要：

In this paper, a new all-optical switching structure is proposed and analyzed. Switching is accomplished by embedded Kerr nonlinear rods in the coupling region of a photonic crystal directional coupler. We show that by modifying the supermodes dispersion curves, the switch length can be reduced 22％ with respect to similar structures. Finite-Difference Time-Domain and Plane Wave Expansion methods are used to analyze the device characteristics. The results show that the transmission efficiency of the proposed structure has been significantly improved.
