Deep ultra-violet plasmonics

News: March 31, 2022

Our work on probing germanium plasmons through momentum-resolved EELS experiments got published in Optics Express. We reveal the metallic nature of Ge in the DUV regime. This new frontier of DUV plasmonics enables the development of DUV devices based on Ge. Read more about the paper here .

Dipole-dipole interactions in nanophotonics

Single photon pulse induced transient entanglement force We show that a single photon pulse incident on two interacting two-level atoms induces a transient entanglement force between them. After absorption of a multi-mode Fock state pulse, the time-dependent atomic interaction mediated by the vacuum...
