Abstract

Various applications, such as demultiplexing, clock recovery, or all-optical signal regeneration have been demonstrated using nonlinear optical loop mirrors (NOLM), where the nonlinear effects were either spread over the fiber, due to cross phase modulation, or concentrated on a nonlinear element such as a semiconductor optical amplifier (SOA) undergoing cross gain saturation [1]. This paper addresses the last configuration and its application in all-optical regeneration.
