Abstract An all optical 2*4 decoder will be designed and proposed in this paper. Nonlinear photonic crystal ring resonators are used for realizing the proposed decoder. Nonlinear photonic crystal ring resonators will be achieved by introducing nonlinear rods made of doped glass around the core section of the resonator. In the proposed structure X and Y port was used to switch the optical beams coming from E between O0, O1, O2 and O3 output ports. The optical intensity required for performing the switching task is about 50 W/μm2. The maximum switching frequency and the total footprint of the proposed are 10 GHz, and 581 μm2. Reduced input optical intensity and compactness are the main characteristics of the present work. Numerical methods such as plane wave expansion and finite difference time domain were used for performing the required calculations.
