Paper Abstract

Laser phase noise manifests itself as a degradation in SNR or BER in coherent optical communication systems. Real systems, particularly those employing phase modulation, often require sub-megahertz linewidth sources to perform satisfactorily. Experimental laboratory systems offer greater flexibility in their realisation and in this paper a novel technique is described to reduce the effective linewidth of semiconductor lasers, which is appropriate to such laboratory experiments.
