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.

Claim (Index 1):
A device comprising:\n a light source configured to produce an optical signal; an optical waveguide configured to receive and convey the optical signal from the light source; an optical ring resonator configured to least one of: modulate and filter the optical signal on the optical waveguide; a heater positioned to heat the optical ring resonator; a controller configured to:\n control the light source to produce the optical signal at a power that shifts a resonance wavelength of the optical ring resonator by at least 10 picometers, due to self-heating; and \n prior to at least one of modulating and filtering the optical signal at the optical ring resonator, control the heater to an operating temperature, from either a high-to-low temperature adjustment direction or a low-to-high temperature adjustment direction, at which the resonance wavelength of the optical ring resonator is greater than a respective wavelength of the optical signal, wherein at a given level of self-heating a peak in an extinction ratio of the optical ring resonator as a function of heater temperature is outside of a hysteresis region.
