Micro-sized tunable liquid crystal optical filters
Caleb Stoltzfus, Russell Barbour, David Atherton +1
Liquid Crystal Arrayed Microcavities (LCAM) is a new technology for ultra-narrow optical filtering (FWHM ~ 0.1 nm) that uses pico-liter volume Fabry-Perot type optical cavities fil…
Longitudinal spin-relaxation of donor-bound electrons in direct bandgap semiconductors
Todd Karin, Xiayu Linpeng, M. V. Durnev +6
We measure the donor-bound electron longitudinal spin-relaxation time () as a function of magnetic field () in three high-purity direct-bandgap semiconductors: GaAs, InP, a…
Radiative properties of multi-carrier bound excitons in GaAs
Todd Karin, Russell Barbour, Charles Santori +3
Excitons in semiconductors can have multiple lifetimes due to spin dependent oscillator strengths and interference between different recombination pathways. In addition, strain and…
Waveguide-integrated single-crystalline GaP resonators on diamond
Nicole Thomas, Russell J. Barbour, Yuncheng Song +2
Large-scale entanglement of nitrogen-vacancy (NV) centers in diamond will require integration of NV centers with optical networks. Toward this goal, we present the fabrication of s…
Room-temperature detection of single 20 nm super-paramagnetic nanoparticles with an imaging magnetometer
Michael Gould, Russell Barbour, Nicole Thomas +3
We demonstrate room temperature detection of single 20 nm super-paramagnetic nanoparticles (SPNs) with a wide-field optical microscope platform suitable for biological integration.…
Laser micro-fabrication of concave, low-roughness features in silica
David Hunger, Christian Deutsch, Russell J. Barbour +2
We describe a micro-fabrication method to create concave features with ultra-low surface roughness in silica, either on the end facets of optical fibers or on flat substrates. The…
Laser spectroscopy of individual quantum dots charged with a single hole
B. D. Gerardot, R. J. Barbour, D. Brunner +6
We characterize the positively charged exciton (X1+) in single InGaAs quantum dots using resonant laser spectroscopy. Three samples with different dopant species (Be or C as accept…
Storing light as a mechanical excitation in a silica optomechanical resonator
Victor Fiore, Yong Yang, Mark Kuzyk +3
We report the experimental demonstration of optomechanical light storage in a silica resonator. We use writing and readout laser pulses tuned to one mechanical frequency below an o…
