Abstract

A comprehensive theoretical model of the semiconductor optical amplifier (SOA)-based ultrafast nonlinear interferometer (UNI) in counter-propagating configuration is presented. The model consists of a set of equations that describe the gain and phase dynamics of an SOA deployed as the nonlinear element in an interferometric switch. By undertaking an extensive numerical analysis, the transmission response of the UNI is calculated with respect to the key temporal parameters of the SOA transit time, the time delay between the two copies of the clock signal to be switched, and the width of the control pulses that alter the SOA properties. The obtained simulation results allow us to investigate the simultaneous influence of these parameters on the switching window and effectively correlate them to derive an operational condition that must necessarily hold in order to achieve satisfactory operation. The thorough study of this condition enables us to specify the restrictions imposed on each involved parameter and extract useful design rules concerning their proper selection and combination so as to ensure optimum performance. The proposed model can provide the framework for studying more complex, combinatorial all-optical circuits of enhanced functionality in which the UNI is the core switching module.
