All-optical pseudo noise sequence generator using a micro-ring resonator

Abstract

A scheme for the generation of a pseudo noise (PN) sequence in the optical domain is proposed. The cascaded units of micro-ring resonator (MRR)-based D flip-flop are used to design the device. D flip-flops consist of a single MRR and share the same optical pump signal. Numerical analysis is performed, and simulated results are discussed. The proposed device can be used as a building block for optical computing and for creating an information processing system.
