An effective density matrix approach for intersubband plasmons coupled to a cavity field: electrical extraction/injection of intersubband polaritons
M. Lagrée, M. Jeannin, G. Quinchard +5
The main technological obstacle hampering the dissemination of modern optoelectronic devices operating with large light-matter coupling strength is an in-depth comprehension of…
