SOA-based optical switches

A. Assadihaghi, H. Teimoori and T.J. Hall,     University of Ottawa, Canada


The application of semiconductor optical amplifiers (SOAs) is not limited only to the amplification of optical signals. It is also used as an important element in optical switching, all-optical signal processing, demultiplexing, regeneration and wavelength conversion. The goal of this chapter is to present design criteria, improvement of the performance and integration of the SOA-based switches. We begin with a description of SOA-based switch architectures in the second section. The physical structure of an SOA, its features and characteristics are presented in the third section. Some techniques for SOA design improvements and ...
