    Sub-microsecond thermal reconfiguration of silicon photonic devices
    (Georgia Institute of Technology, 2009-10) Atabaki, Amir H. ; Eftekhar, Ali A. ; Yegnanarayanan, Siva ; Adibi, Ali
    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.

    Sustained GHz oscillations in ultra-high Q silicon microresonators
    (Georgia Institute of Technology, 2009) Soltani, Mohammad ; Yegnanarayanan, Siva ; Li, Qing ; Atabaki, Amir ; Eftekhar, Ali A. ; Adibi, Ali
    We report the experimental observation of long-sustained GHz electronic oscillations resulting from coupled electron-photon dynamics in ultra-high-Q Si microdisk resonators with CW pumping. Theoretical analysis identifies conditions for steady-state GHz oscillations while suppressing thermal oscillations.
