未来的全光信号处理应用可能需要使用通过单个光耦合器件的多个光信号。本文研究了一种改进的模型，用于模拟两个光信号通过光耦合法布里-珀罗半导体光放大器（FP-SOA）。这些信号的光功率和相位都被建模，以及FP-SOA的光增益。本文的改进模型是基于一个用于研究单个光信号的光学双稳性的改进模型，其中内功率与输出功率之间的关系是考虑法布里-珀罗结构的表达式。已开展工作，将所有模型放入一致的符号中。由此产生的，改进的双信号操作模型表明，较低的临界功率触发动作。
Future all-optical signal processing applications may require the use of multiple optical signals passing through a single, optically bistable device. My thesis investigates an improved model for modeling two optical signals passing through an optically bistable Fabry-Perot semiconductor optical amplifier (FP-SOA). The optical power and phase of these signals are both modeled, as well as the optical gain of the FP-SOA. My improved model is based on an improved model used to study optical bistability of just a single optical signal, in which the internal power is related to the output power with an expression accounting for the Fabry-Perot structure. Work has been performed to put all models into a consistent notation. The resulting, improved model for dual-signal operation indicates lower critical powers to trigger bistable action.
