All-Optical Signal Processing Subsystems Based on Highly Non-linear Fibers and Their Limitations for Networking Applications

Abstract

Abstract. All optical signal processing is a fundamental concept on which the next generation networks will be based. Implementation of key functionalities as multiwavelength regeneration, frequency conversion and high data rate demultiplexing performed all optically becomes a primary target in current research scenario. In this work, demultiplexing of high data rate signals is demonstrated. The base for the functionality is the cross phase modulation occurring in a span of highly non linear fiber. This fiber is designed to have low birefringence, therefore quite adapted for processing polarization dependent processes, which are the base for the achieved functionality. Demultiplexing from 40GHz and 80GHz to 10GHz is demonstrated.
