A simple method has been proposed to use four-wave mixing to design and simulate the all-optical AND logic gate in a photonic crystal semiconductor optical amplifier (PC-SOA) that is integrated with an ideal optical bandpass filter. The preferred logical function could be carried out in the proposed scheme with no use of a continuous-wave signal. Nonlinearities including carrier depletion, carrier heating, and spectral hole burning have been considered in the presented simulations. Furthermore, for improvement of the AND logic gate performance, the impacts of the pattern effect of the signals propagating in the PC-SOA medium, the input signal bit rate effects, and gain recovery have been extensively investigated. The findings demonstrated that the optimal output signal featuring 3-fJ energy and 2-mA injection current could be achieved at a bit rate of 50 Gbps.

四波混频在光子晶体半导体光放大器中设计和模拟全光AND逻辑门的用途

已经提出了一种简单的方法，该方法使用四波混频来设计和仿真与理想光学带通滤波器集成在一起的光子晶体半导体光放大器（PC-SOA）中的全光AND逻辑门。可以在提出的方案中执行优选的逻辑功能，而无需使用连续波信号。在提出的仿真中已经考虑了非线性，包括载流子耗尽，载流子加热和光谱孔燃烧。此外，为了提高与逻辑门的性能，已经广泛研究了在PC-SOA介质中传播的信号的图案效应，输入信号比特率效应和增益恢复的影响。
