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…
