Abstract

In optical code division multiple access (OCDMA), the optical bandwidth is accessed simultaneously by multiple users, leading to intensity noise in photodetection. In this article we focus on spectral amplitude encoded CDMA for access networks. We examine efficient system architectures, practical implementations, compare the impact of different system designs on spectral efficiency and bit error rates. We draw on both experimental and simulation results. We discuss the use of two types of optical sources, a broadband incoherent source and a multi-laser source. We examine the capacity that can be achieved for these systems and the design goals we are shooting for in our laboratory.
