Integrated TiO2 resonators for visible photonics
Jennifer T. Choy, Jonathan D. B. Bradley, Parag B. Deotare +4
We demonstrate waveguide-coupled titanium dioxide (TiO2) racetrack resonators with loaded quality factors of 2x10^4 for the visible wavelengths. The structures were fabricated in s…
A study of thermally-induced optical bistability and the role of surface treatments in Si-based mid-infrared photonic crystal cavities
Raji Shankar, Irfan Bulu, Rick Leijssen +1
We report the observation of optical bistability in Si-based photonic crystal cavities operating around 4.5 \mum. Time domain measurements indicate that the source of this optical…
Deterministic design of wavelength scale, ultra-high Q photonic crystal nanobeam cavities
Qimin Quan, Marko Loncar
Photonic crystal nanobeam cavities are versatile platforms of interest for optical communications, optomechanics, optofluidics, cavity QED, etc. In a previous work \cite{quan10}, w…
High-Q/V air-mode photonic crystal cavities at microwave frequencies
Yinan Zhang, Irfan Bulu, Wai-Ming Tam +4
We present results for a photonic microwave resonator designed and fabricated at 17.4GHz with a record high Quality factor (Q = 26,400) at room temperature over a mode volume small…
Plasmonic resonators for enhanced diamond NV- center single photon sources
Irfan Bulu, Thomas Babinec, Birgit Hausmann +2
We propose a novel source of non-classical light consisting of plasmonic aperture with single-crystal diamond containing a single Nitrogen-Vacancy (NV) color center. Theoretical ca…
Bonding, antibonding and tunable optical forces in asymmetric membranes
Alejandro W. Rodriguez, Alexander P. McCauley, Pui-Chuen Hui +5
We demonstrate that tunable attractive (bonding) and repulsive (anti-bonding) forces can arise in highly asymmetric structures coupled to external radiation, a consequence of the b…
