Paper Abstract

The feasibility of operating the semiconductor optical amplifier (SOA)–based ultrafast nonlinear interferometer (UNI) in nontrivial switching mode is methodically investigated and demonstrated. For this purpose, a comprehensive model that simulates the dynamical behavior of an SOA subject to an ultra-high-speed pseudorandom binary sequence is appropriately adapted to the case of the specific configuration. By undertaking a detailed theoretical treatment, the impact of the most important SOA parameters on the fully loaded Q-factor is thoroughly analyzed and assessed, enabling us to extract useful design rules for their proper selection so as to ensure enhanced error-free performance at the desired output port of the considered interferometric arrangement. The outcome of this effort may assist the study and implementation of all-optical circuits and subsystems of nontrivial functionality, in particular with feedback, in which the UNI employing a SOA as the nonlinear element is the core logical module.
