Automated Vector-Scanning Spectroscopy for Large-Scale Characterization of Single Quantum Emitters

William Eshbaugh, Ashish Chanana, Edgar Perez +13

The inherent spatial randomness and broad spectral heterogeneity of epitaxial quantum dots (QDs) -- one of the most mature classes of solid-state quantum emitters -- remains a majo…

Integrated broadband optical isolator via dynamic rotating destructive interference

Kyunghun Han, Yiliang Bao, Junyeob Song +7

Photonic integrated circuits route and shape light on a chip, but back-reflections feed back into coherent on-chip lasers, destabilizing operation and corrupting signals. Robust op…
