Analytical study and effective control of all-optical switches in fiber lasers

Abstract The all-optical switch is an important device in the all-optical network, and is widely used in optical network protection, network performance monitoring and testing. In this paper, all-optical switches in fiber lasers are investigated analytically. An effective method is suggested to control the related characteristics of all-optical switches through soliton interactions. The effects of corresponding parameters on the performance of all-optical switches are discussed in detail. Results of this paper is helpful to improve the all-optical switching speed and the work efficiency of the all-optical network in nonlinear optics.
