A novel technique to cancel laser phase noise in coherent receivers is proposed. The equivalent laser linewidth is reduced by a factor of 10, and coherent detection of DQPSK signals affected by strong phase noise is experimentally demonstrated.

Abstract
A novel technique to cancel laser phase noise in coherent receivers is proposed. The equivalent laser linewidth is reduced by a factor of 10, and coherent detection of DQPSK signals affected by strong phase noise is experimentally demonstrated.File in questo prodotto:
