Abstract

In this paper, carrier reservoir semiconductor optical amplifiers (CR-SOAs) are utilized for the first time in designing an all-optical 2 × 1 multiplexer with enable function, operating at 120 Gb/s. Traditional SOAs face challenges with slow carrier recovery, restricting their application in high-speed scenarios. CR-SOA, with a carrier reservoir near the active region, replenishes carriers quickly, enabling faster gain and phase recovery. For the first time, a 2 × 1 multiplexer with an enable input is proposed, adding flexibility and control for dynamic data routing in optical systems. Basic gates such as AND, OR, and NOT gates have been designed using this multiplexer, with the enable input enhancing their versatility. The performance of the multiplexer and gates is evaluated using metrics like quality factor, extinction ratio, contrast ratio, and eye opening factor. The quality factor is analyzed concerning parameters such as amplified spontaneous emission, data rate, carrier transition time, and injection current. Simulation results confirm the functionality of the 2 × 1 multiplexer and logic gates, demonstrating satisfactory performance at high data rates.

设计和分析基于载波水库 SOA 的 2 × 1 MUX（带使能输入），并在 120 Gb/s 速率下使用 MUX 实现基本逻辑门

本文首次利用载波贮存半导体光放大器（CR-SOAs）设计了具有使能功能的全光 2 × 1 多路复用器，其工作频率为 120 Gb/s。传统 SOA 面临载波恢复慢的挑战，限制了其在高速场景中的应用。CR-SOA在有源区附近设有载流子储存器，可快速补充载流子，从而实现更快的增益和相位恢复。我们首次提出了带有使能输入的 2 × 1 多路复用器，为光学系统中的动态数据路由增加了灵活性和控制性。利用这种多路复用器设计了 AND、OR 和 NOT 等基本门，使能输入增强了它们的多功能性。使用品质因数、消光比、对比度和开眼因子等指标对多路复用器和门的性能进行了评估。品质因数的分析涉及放大自发辐射、数据速率、载波转换时间和注入电流等参数。仿真结果证实了 2 × 1 多路复用器和逻辑门的功能，在高数据速率下表现出令人满意的性能。
