Abstract

Four-wave mixing (FWM) has recently attracted great attention for wavelength conversion and phase conjugation. It offers strict transparency in wavelength conversion, where the use of any modulation format is permitted. In order for a FWM-based device to be practical, various polarisation independent mechanisms have been proposed and demonstrated which include the polarisation diversity technique and the orthogonally-polarised pumps technique. In this paper, we analyse the noise properties of polarisation independent four-wave mixing based on the orthogonally-polarised pumps technique. Noise reduction using fibre gratings is experimentally demonstrated, for the first time, in a dual-pump polarisation independent four-wave mixer. A power penalty improvement in excess of 5 dB in a 10 Gbit/s RZ system is achieved.
