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