Abstract
Two concepts of performing All-Optical Wavelength conversion are presented and discussed. The novelty of this manuscript is in presenting a configuration providing increased extinction ratio of conversion. Both concepts are based on the photorefractive effect in crystals. By generating diffractive photo refractive pattern we improve the conversion extinction ratio. In the first concept two beam pairs are used to create two index gratings in the medium and by that receive wavelength conversion. In the second concept, the fanning effect in the photorefractive medium is used to perform wavelength conversion using only one beam pair. Proof-of-Principle experiments results are presented.
