摘要

本文利用光子晶体中In0.82Ga0.18As0.40P0.60棒的二维方形晶格中的克尔效应，提出了一种超紧凑的全光非逻辑门。主要的设备操作是基于所有光开关的概念。在我们的工作中，新颖之处在于基于硅纳米晶体“Si-Nc /In0.82Ga0.18As0.40P0.60”材料的组合设计了一种新的简单非线性环，可以使用。该非逻辑门的对比度和延迟时间分别为25.52 dB和0.66 ps，结构尺寸为168 μm2。所设计的逻辑门具有能耗低、响应速度快、结构紧凑、易于集成等特点。所有的模拟都是基于非线性时域有限差分(NL-FDTD)和平面波展开(PWE)数值方法。

Optimization of an All-Optical Photonic Crystal NOT Logic Gate Using Switch Based on Nonlinear Kerr Effect and Ring Resonator

In this paper, the use of the Kerr effect in a two-dimensional square lattice of In0.82Ga0.18As0.40P0.60 rods in photonic crystal proposes an ultra-compact all-optical NOT logic gate. The main device operation is based on the concept of all the optical switches. In our work, the novelty lies in the design of a new simple nonlinear ring based on the combination of silicon nano-crystal "Si–Nc/In0.82Ga0.18As0.40P0.60" materials that can be used. The contrast ratio and delay time for the proposed NOT logic gate are respectively 25.52 dB and 0.66 ps. The structure size is equal to 168 μm2. Designed logic gates are characterized by low energy consumption, high-speed response, compactness and easy integration. All simulations are based on Non-Linear-Finite Difference Time Domain (NL-FDTD) and Plane Wave Expansion (PWE) numerical methods.
