Four-Wave Mixing in Photonic Crystal Fibres for Wavelength Conversion in Optical Networks

Abstract: Four-Wave Mixing is one of the few all-optical techniques which provides fully transparent wavelength conversion. Here, we demonstrate Four-Wave Mixing generation in a band of up to 20 nm centred at the zero dispersion wavelength of a photonic crystal fibre (1560 nm). A stable efficiency around-35 dB is maintained across the band using a pump power of 10 dBm. The experimental results are in good agreement with the theoretical results. 1. Introduction. Photonic crystal fibre (PCF) technology has recently witnessed a great evolution and is of great interest for fibre device applications because of the wide range of novel optical properties that it offers. Its structure can provide a much higher effective nonlinearity than a conventional fibre. As
