Four-wave-mixing based optical wavelength converter device

摘要

Wavelength converter device for generating a converted radiation at frequency Omega_g through interaction between at least one signal radiation at frequency Omega_g and at least one pump radiation at frequency Omega_g, with an input for the at least one signal radiation at frequency Omega_g; a pump light source for generating the at least one pump radiation at frequency Omega_g, an output for taking out the converted radiation at frequency Omega_g, a structure for transmitting the signal radiation, the structure including one optical resonator having a non-linear material, having an optical length of at least 40*eta/2, wavelength eta being the wavelength of the pump radiation, and resonating at the pump, signal and converted frequencies Omega_p, Omega_s, and Omega_g. The structure has a further optical resonator coupled in series to the optical resonator, the further optical resonator having a non-linear material, having an optical length of at least 40*eta/2, wherein eta is the wavelength of the pump radiation, and resonating at the pump, signal and converted Omega_p, Omega_s and Omega_g, wherein by propagating through the structure, the pump and signal radiation generate the converted radiation by non-linear interaction within the optical resonators.
