A scalable gallium-phosphide-on-diamond spin-photon interface
Nicholas S. Yama, Chun-Chi Wu, Fariba Hatami +1
The efficient interfacing of quantum emitters and photons is fundamental to quantum networking. Quantum defects embedded in integrated nanophotonic circuits are promising for such…
Rapid, in-situ neutralization of nitrogen- and silicon-vacancy centers in diamond using above-band-gap optical excitation
Christian Pederson, Nicholas S. Yama, Lane Beale +2
The charge state of a quantum point defect in a solid state host strongly determines its optical and spin characteristics. Consequently, techniques for controlling the charge state…
Selective active resonance tuning for multi-mode nonlinear photonic cavities
Alan D. Logan, Nicholas S. Yama, Kai-Mei C. Fu
Resonant enhancement of nonlinear photonic processes is critical for the scalability of applications such as long-distance entanglement generation. To implement nonlinear resonant…
Creation of color centers in diamond by recoil implantation through dielectric films
Yuyang Han, Christian Pederson, Bethany E. Matthews +3
The need of near-surface color centers in diamond for quantum technologies motivates the controlled doping of specific extrinsic impurities into the crystal lattice. Recent experim…
Silicon-lattice-matched boron-doped gallium phosphide: A scalable acousto-optic platform

The compact size, scalability, and strongly confined fields in integrated photonic devices enable new functionalities in photonic networking and information processing, both classi…
Hybrid Integration of GaP Photonic Crystal Cavities with Silicon-Vacancy Centers in Diamond by Stamp-Transfer
Srivatsa Chakravarthi, Nicholas S. Yama, Alex Abulnaga +6
Optically addressable solid-state defects are emerging as one of the most promising qubit platforms for quantum networks. Maximizing photon-defect interaction by nanophotonic cavit…
Optical manipulation of layer-valley coherence via strong exciton-photon coupling in microcavities
Mandeep Khatoniar, Nicholas Yama, Areg Ghazaryan +4
Coherent control and manipulation of quantum degrees of freedom such as spins forms the basis of emerging quantum technologies. In this context, the robust valley degree of freedom…
Triply-Resonant Sum Frequency Conversion with Gallium Phosphide Ring Resonators
Alan D. Logan, Shivangi Shree, Srivatsa Chakravarthi +5
We demonstrate quasi-phase matched, triply-resonant sum frequency conversion in 10.6-um-diameter integrated gallium phosphide ring resonators. A small-signal, waveguide-to-waveguid…
Optical Valley Hall Effect of 2D Excitons in Hyperbolic Metamaterial
Sriram Guddala, Mandeep Khatoniar, Nicholas Yama +3
The robust spin and momentum valley locking of electrons in two-dimensional semiconductors make the valley degree of freedom of great utility for functional optoelectronic devices.…
