Dynamic tuning of optical cavities enables rich new capabilities that operate with low power, are linear, efficient, compact and CMOS compatible. These dynamic devices are based on the fundamental principle that light propagating within a cavity must inherently match the properties of the cavity at all times. Therefore, when the cavity is dynamically tuned - the lights properties are being directly changed. Consequently, these dynamically tuned silicon nanophotonic devices enable rich new tools for processing optical signals, including, linear wavelength converters, rapidly tunable optical delay devices and robust electro-optic modulators. The following key discoveries were made 1 Tunable optical delay that enables a 1000x slowing of light in a 100micron Silicon microring resonator structure 2 Wavelength conversion at the single photon level by dynamically tuning a microring resonator 3 Temporal and spectral models of resonators operating in the quantum optical regime 4 Resonant Hong-Ou-Mandel effect that will enable robust quantum computation and sensing 5 Robust Phase Shift Keyed Electro-optic Modulators 6 Efficient micro-oven heater to enhance the thermo-optic tuning of Silicon photonic devices.
