Description
Summary:All optical photonic crystal based logic gates are believed to be essential components for compact photonic integrated circuits and Wavelength Division Multiplexing (WDM) systems. One of the promising designs for a logic gate is based on the photonic crystal ring resonators (PhCRR). In this paper, we carried out a performance analysis of a new simple shape of a PhCRR as a function of the nonlinear rods emplacement to pick up the best case offering the maximum transmission efficiency. Then, the optimal case is used for the design of ultra fast all optical gates (OR, AND, NAND). In our work, the novelty lies in the design of a new simple nonlinear ring based on the combination of GaAs/In 0.53 Ga 0.47 As materials that can be used, with the minimum required power (0.733 KW/µm 2 ), to ensure different logic gates’ functionalities. Simulations performed by Numerical methods such as plane wave expansion (PWE) and finite difference time domain (FDTD) demonstrate that the proposed PhCRR has a high quality factor (Q) of about 1719 and a high transmission efficiency of 100%. Moreover, designed logic gates are characterized by its low energy consumption, its ultrafast response, its compactness and its simplicity of integration.
