Electronic signal processing for Optical Code Division Multiple Access Networks

Abstract

This work demonstrates the potential of electronic signal processing for applications in optical code division multiple access networks. The proposed designs are based in distributed topologies allowing operation at speeds close to the cut-off frequency of the transistors employed. We discuss structures capable of encoding and decoding time-domain and multi-wavelength optical CDMA signals. A scheme for mitigating of the impact of group velocity dispersion in multi-wavelength OCDMA systems is also analysed.
