Abstract
All-optical wavelength converters based upon difference frequency generation (DFG) in optical chips with periodically poled materials are presented. Tunable continuous wave (CW) laser sources and various arrangements are made with the optical input signals in different ITU channels. In some arrangements the laser source(s) acts as the pump for the conversion of the input signals to different wavelengths. In other arrangement, the amplified input signals acts as a pump with the laser source in the role of the input signal. The net effect is that input signals are converted to different wavelengths. One-to-any, any-to-one, and any-to-any wavelength converters are described. Simultanenous conversation can also be preformed so that bands of signals may also be converted.
