Abstract:
A device and method for tuning a ring resonator using self-heating stabilization is provided. A light source is controlled to produce an optical signal, input to an optical ring resonator, at a power where self-heating shifts a resonance wavelength of the optical ring resonator by at least 10 picometers, the self-heating comprising absorption in the optical ring resonator of optical power from a received optical signal. Prior to using the optical ring resonator at least one of modulate and filter the optical signal at the optical ring resonator, a heater of the optical ring resonator is controlled to an operating temperature at which the resonance wavelength of the optical ring resonator is greater than a respective wavelength of the optical signal.
