Abstract
The invention concerns a method for tuning at a targeted resonance wavelength at least one micro and/or nanophotonic resonator, the resonator having dimensions defining resonance wavelength of said resonator, the resonator being immersed in a fluid containing ions so that the resonator is surrounded by said fluid, wherein the method comprises a step of injecting light, having a light wavelength equal to the resonance wavelength, into the resonator, so that the injected light resonates within the resonator and triggers a photo-electrochemical etching process enabled by the surrounding fluid containing ions, said etching process being enhanced by the optical resonance which amplifies light intensity in the photonic resonator, the etching decreasing dimensions of the photonic resonator, hereby lowering and tuning the resonance wavelength of the photonic resonator.
