Methods and devices for maintaining a resonant wavelength of a photonic microresonator

Patent Number: 9,081,135

Official Filing: View the Complete Patent
Abstract: A photonic microresonator incorporates a localized heater element within a section of an optical bus waveguide that is in proximity to the resonator structure. The application of an adjustable control voltage to the heater element provides a localized change in the refractive index value of the bus waveguide, compensating for temperature-induced wavelength drift and maintaining a stabilized value of the microresonator's resonant wavelength.
