Error free transmission of SS-WDM using incoherent-to-coherent wavelength conversion

Abstract

This paper reports an all-optical wavelength conversion of an incoherent optical signal to a coherent optical signal using the cross-gain modulation in semiconductor optical amplifiers. Wavelength division multiplexed networks using broadband sources have performance limited by beat noise; conversion from a non-coherent to a coherent signal eliminates beat noise and enables the elimination of the bit error rate floor.
