Abstract:
1. An integrated silicon optical device capable of being monitored and tuned in real-time, comprising: a bus waveguide, comprising an input port and an output port; an optical microresonator coupled to the bus waveguide, configured to selectively receive light at a desired resonance wavelength from the bus waveguide; a photodetector, configured to electrically read out an operation condition of the optical microresonator; a diode-tuner, configured to blueshift or redshift the resonance wavelength of the optical microresonator; a micro-heater, configured to redshift the resonance wavelength of the optical microresonator; and a control unit, comprising a transimpedance amplifier (TIA) and a microprocessor, configured to implement a two-stage closed-loop tuning scheme utilizing the diode-tuner and the micro-heater.
