An All-Optical Digital 2-to-1 Multiplexer Using Photonic Crystal-Based Nonlinear Ring Resonators

摘要

In this paper, we proposed a structure to realize an all-optical digital multiplexer. The proposed structure had two inputs, one control and one output port. Using the control port, one can decide which input port can be connected to the output port. The proposed structure consisted of two nonlinear photonic crystal ring resonators, L-shaped and T-shaped, and a straight waveguide. Total footprint and maximum delay time of the proposed structure were 479m(2) and 3ps, respectively.
