Four-wave-mixing based optical wavelength converter device

摘要

A wavelength converter device is provided for generating a converted radiation at frequency ω_g through interaction between at least one signal radiation at frequency ω_s and at least one pump radiation at frequency ω_p, including an input for the at least one signal radiation at frequency ω_s, a pump light source for generating the at least one pump radiation at frequency ω_p, an output for taking out the converted radiation at frequency ω_g, 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_p, ω_s and ω_g, wherein by propagating through the structure, the pump and signal radiation generate the converted radiation by non-linear interaction within the optical resonators.
