Adiabatic Resonant Microrings (ARMs) with Directly Integrated Thermal Microphotonics

A new class of microphotonic-resonators, Adiabatic Resonant Microrings (ARMs), is introduced. The ARM resonator geometry enables heater elements to be formed within the resonator, simultaneously enabling record low-power (4.4μW/GHz) and record high-speed (1μs) thermal tuning.
