Using the experimental data we show the possibility of sub-microsecond reconfiguration of silicon photonics microresonators through pulse shaping of micro-heater excitation. Also, a novel heater structure based on small microdisk resonators with sub-hundred-nanosecond reconfiguration speed is proposed and investigated theoretically.
Integration of silicon microresonators with metallic micro-heaters optimized for low power consumption and fast reconfigurability is experimentally demonstrated. It is shown that narrower heaters improve the performance and also LPCVD SiN over-cladding enhances tuning speed.
We propose an interferometric coupling scheme for tuning the spacing between resonances in a traveling-wave resonator. 62pm (8 GHz) tuning of resonance spacing is demonstrated in SOI micro-ring resonators integrated with thin-film micro-heaters.
A traveling-wave resonator structure with interferometric-coupling scheme is shown to have the capability of supporting both over-coupled and critically-coupled modes, simultaneously. This device is demonstrated in SOI with an integrated microheater to tune its coupling. The application of this device for nonlinear optics is discussed.
We propose and implement a traveling-wave resonator with an interferometric coupling scheme for efficient high-bandwidth nonlinear silicon photonics. By thermal tuning of the interferometer, selective critical coupling for the pump wavelength is achieved.
