Photo-oxidative tuning of individual and coupled GaAs photonic crystal cavities
Alexander Y. Piggott, Konstantinos G. Lagoudakis, Tomas Sarmiento +3
We demonstrate a new photo-induced oxidation technique for tuning GaAs photonic crystal cavities using a pulsed laser with an average power of . T…
A photonic crystal cavity-optical fiber tip nanoparticle sensor for biomedical applications
Gary Shambat, Sri Rajasekhar Kothapalli, Aman Khurana +8
We present a sensor capable of detecting solution-based nanoparticles using an optical fiber tip functionalized with a photonic crystal cavity. When sensor tips are retracted from…
Electrically driven photonic crystal nanocavity devices
Gary Shambat, Bryan Ellis, Jan Petykiewicz +6
Interest in photonic crystal nanocavities is fueled by advances in device performance, particularly in the development of low-threshold laser sources. Effective electrical control…
Optical fiber tips functionalized with semiconductor photonic crystal cavities
Gary Shambat, J Provine, Kelley Rivoire +3
We demonstrate a simple and rapid epoxy-based method for transferring photonic crystal cavities to the facets of optical fibers. Passive Si cavities were measured via fiber taper c…
Nanobeam Photonic Crystal Cavity Light-Emitting Diodes
Gary Shambat, Bryan Ellis, Jan Petykiewicz +5
We present results on electrically driven nanobeam photonic crystal cavities formed out of a lateral p-i-n junction in gallium arsenide. Despite their small conducting dimensions,…
Nanobeam photonic crystal cavity quantum dot laser
Yiyang Gong, Bryan Ellis, Gary Shambat +3
The lasing behavior of one dimensional GaAs nanobeam cavities with embedded InAs quantum dots is studied at room temperature. Lasing is observed throughout the quantum dot PL spect…
Coupled fiber taper extraction of 1.53 um photoluminescence from erbium doped silicon nitride photonic crystal cavities
Gary Shambat, Yiyang Gong, Jesse Lu +4
Optical fiber tapers are used to collect photoluminescence emission at ~1.5 um from photonic crystal cavities fabricated in erbium doped silicon nitride on silicon. Photoluminescen…
