Technique to improve carrier-to-interference ratio of optical single sideband with carrier modulated signals

Abstract

We propose and demonstrate a simple technique to improve the carrier-to-interference ratio (CIR) of optical single sideband with carrier modulated signals for fiber-radio applications. The proposed scheme is demonstrated via experiment and simulation with a two-tone test showing that an improvement in CIR of 9 dB can be achieved. © 2006 Optical Society of America.
