All Optical Gigabit Switching in a Nonlinear Loop Mirror using Semiconductor Lasers,
Abstract
In a recent paper we demonstrated an all-optical demultiplexer using a nonlinear optical loop mirror (NOLM) in which a signal at one wavelength is used to switch a signal at a different wavelength. The switching signal in that case was generated from a mode-locked Nd-YAG laser at 1.32um operating at 76 MHz and the switched signal was a gain switched DFB laser operating at 1.56um at 1 GHz. The purpose of this present work is to extend the optical switching into the gigabit regime while, at the same time, avoiding high power laser systems.
