Leonardo Midolo develops III-V optoelectronic quantum devices at NBI. Research: (1) nanomechanical quantum photonic integrated circuits (NOEMS) — GaAs waveguide phase shifters, routers, and switches for single-photon routing; (2) heterogeneous integration of quantum dot emitters on silicon and SiN platforms; (3) quantum key distribution with deterministic single-photon sources over field-installed dark fibre. Group established 2022; Beamfox spinout for proximity correction.

Ying Wang (assistant professor in Quantum Optoelectronic Devices group) researches GaAs-based integrated photonics for quantum applications: electro-optical quantum dot devices, GaAs-on-insulator waveguide integration, and chip-scale quantum photonics for sensing and QKD.
