Abstract
An all-photonic method to cause a WGM resonator to self-tune to a given wavelength is described. Such all photonic approaches include simply superimposing intense light of a wavelength in a range different from that of a signal wave. The wavelength of the pass band for the signal wavelength can be tuned by adjusting the wavelength (and/or the intensity) of the intense light.
