Dipole nanolasers: A study of their quantum properties

In this paper we undertake a theoretical study of the quantum properties of a dipole nanolaser proposed by Protsenko [Phys. Rev. A 71, 063812 (2005)]. The dynamics of the system is studied in both density-matrix and quantum Langevin formulations, with attention directed to noise sources. The result of the analysis indicates that in the most directly accessible parameter regime, photons will be emitted in a broad spectral distribution and the time delay between consecutive emissions of single photons exceeds the coherence time. Another parameter regime exists within which the emitted light more closely resembles conventional laser light.
