Simulations of an OSNR-Limited All-Optical Wavelength Conversion Scheme [PDF]
IEEE Photonics Technology Letters, 2013 We present simulations of a scheme to perform wavelength conversion of signals that eliminates phase-noise transfer from the pump to the converted signal. Nondegenerate four-wave mixing in a semiconductor optical amplifier is used to convert the signal to a new wavelength, and if an optical comb generator is used as the multiple-pump source, then the ...
