Purcell-enhanced single-photon generation from CsPbBr quantum dots in in-situ selected Laguerre-Gaussian modes
Virginia Oddi, Darius Urbonas, Etsuki Kobiyama +9
Single photons in Laguerre-Gaussian (LG) beams, which carry orbital angular momentum (OAM), could enable more robust and efficient photonic quantum communication and information pr…

Integrated, ultrafast all-optical polariton transistors with sub-wavelength grating microcavities
Pietro Tassan, Darius Urbonas, Bartos Chmielak +7
All-optical logic has the potential to overcome the operation speed barrier that has persisted in electronic circuits for two decades. However, the development of scalable architec…

Room-temperature cavity exciton-polariton condensation in perovskite quantum dots
Ioannis Georgakilas, David Tiede, Darius Urbonas +13
The exploitation of the strong light-matter coupling regime and exciton-polariton condensates has emerged as a compelling approach to introduce strong interactions and nonlineariti…
