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…
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…
Target-wavelength-trimmed second harmonic generation with gallium phosphide-on-nitride ring resonators
Lillian Thiel, Alan D. Logan, Srivatsa Chakravarthi +4
We demonstrate post-fabrication target-wavelength trimming with a gallium phosphide on silicon nitride integrated photonic platform using controlled electron-beam exposure of hydro…
Inverse-designed photon extractors for optically addressable defect qubits
Srivatsa Chakravarthi, Pengning Chao, Christian Pederson +6
Solid-state defect qubit systems with spin-photon interfaces show great promise for quantum information and metrology applications. Photon collection efficiency, however, presents…
400%/W second harmonic conversion efficiency in -diameter gallium phosphide-on-oxide resonators
Alan D. Logan, Michael Gould, Emma R. Schmidgall +7
Second harmonic conversion from 1550~nm to 775~nm with an efficiency of 400% W is demonstrated in a gallium phosphide (GaP) on oxide integrated photonic platform. The platfo…
Frequency control of single quantum emitters in integrated photonic circuits
Emma R. Schmidgall, Srivatsa Chakravarthi, Michael Gould +4
Generating entangled graph states of qubits requires high entanglement rates, with efficient detection of multiple indistinguishable photons from separate qubits. Integrating defec…
