Ultrafast two-photon emission in a doped semiconductor thin film

12 Jan 2020 Hu Futai Li Liu Liu Yuan Meng Yuan Gong Mali Yang Yuanmu

As a high-order quantum transition, two-photon emission has an extremely low occurrence rate compared to one-photon emission, thus having been considered a forbidden process. Here, we propose a scheme that allows ultrafast two-photon emission, leveraging highly confined surface plasmon polariton modes in a degenerately-doped, light-emitting semiconductor thin film...
