1. A method, comprising:
receiving input light having an input wavelength in a first optical resonator for causing resonance of the input light in the first optical resonator so that at least a portion of the input light is converted to a combination of first output light having a first output wavelength that is different from the input wavelength and second output light having a second output wavelength that is different from the input wavelength and the first output wavelength; and
coupling the first output light and the second output light from the first optical resonator to a second optical resonator configured for causing resonance of light having the first output wavelength and light having the second output wavelength.
