In this paper, we report our recent studies on developing nonlinear techniques based on a single SOA for all-optical signal processing at high-speed, with a focus on simple configurations employing commercial SOAs for several key all-optical network applications. Our researches are based on nonlinear polarization rotation (NPR), four-wave mixing (FWM) and cross-phase modulation (XPM) effects in a single SOA. We propose and demonstrate applications of the nonlinear techniques in all-optical logic gates, multi-function format coversion, tunable Lyot birefringent filter and multi-channel optical time division multiplexed (OTDM) demultiplexing.

Abstract By exploiting the phenomena of optical switching, different logic functions for all-optical digital signal processing has been projected. This paper presents the application of optical switching to design of all-optical half adder and half subtractor by Mach-Zehnder interferometer. All-Optical half adder and half subtractor are designed with the optimized structure of 2 × 2 Mach-Zehnder interferometer switch by electro-optic effect in lithium niobate. Numerical simulations of the proposed structure have been conducted to verify the suitability of the designed structure using Opti-BPM software. The implementation of proposed structures is simulated in MATLAB software along with the mathematical description. It is interesting to analyze that the proposed structures are useful to generate combinational and sequential logic circuits in high-speed optical signal processing and switching network.
