Monitoring stimulated emission at the single photon level in one-dimensional atoms

TL;DR

This paper theoretically explores stimulated emission at the single photon level in one-dimensional atoms, analyzing transient and steady states, effects of dephasing, and proposing a scheme for demonstrating optical stimulation in three-level systems.

Contribution

It introduces a theoretical framework for observing stimulated emission at the single photon level in 1D atoms and proposes a novel scheme for optical stimulation in three-level systems.

Findings

Stimulated emission signatures can be observed at the single photon level.

Pure dephasing effects are significant and detectable with current solid state devices.

A new scheme is proposed for demonstrating optical stimulation in three-level 1D atoms.

Abstract

We theoretically investigate signatures of stimulated emission at the single photon level for a two-level atom interacting with a one-dimensional light field. We consider the transient regime where the atom is initially excited, and the steady state regime where the atom is continuously driven with an external pump. The influence of pure dephasing is studied, clearly showing that these effects can be evidenced with state of the art solid state devices. We finally propose a scheme to demonstrate the stimulation of one optical transition by monitoring another one, in three-level one-dimensional atoms.
