A wavelength converter device is provided for generating a converted radiation at frequency omega<SUB>g </SUB>through interaction between at least one signal radiation at frequency omega<SUB>s </SUB>and at least one pump radiation at frequency omega<SUB>p</SUB>, including an input for the at least one signal radiation at frequency omega<SUB>s</SUB>, a pump light source for generating the at least one pump radiation at frequency omega<SUB>p</SUB>, an output for taking out the converted radiation at frequency omega<SUB>g</SUB>, a structure for transmitting the signal radiation, including two optical resonators having a non-linear material, having an optical length of at least 40*lambda/2, lambda being the wavelength of the pump radiation, and resonating at the pump, signal and converted frequencies omega<SUB>p</SUB>, omega<SUB>s </SUB>and omega<SUB>g</SUB>, wherein by propagating through the structure, the pump and signal radiation generate the converted radiation by non-linear interaction within the optical resonators.
