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…

Transition between cooperative emission regimes in giant perovskite nanocrystals
Etsuki Kobiyama, Gabriele Rainò, Yuliia Berezovska +6
Interactions between emitters within an ensemble can give rise to cooperative processes that significantly alter the properties of the emitted light. One such process is superfluor…
