This work extends their calculations, taking fully into account the phase diffusion of the laser field, and considering different dynamical regimes to obtain large-amplitude squeezing in the second-harmonic output if the cavity loss rate at the second harmonic is high compared to the atomic decay rates.Abstract:
We consider second-harmonic generation within a laser cavity. Garcia-Fernandez et al. [Quantum Opt. 2, 49 (1990)] found that large-amplitude squeezing may be obtained in the fundamental output if the cavity loss rates are high compared to the atomic decay rates. We extend their calculations, taking fully into account the phase diffusion of the laser field, and considering different dynamical regimes. We obtain large-amplitude squeezing in the second-harmonic output if the cavity loss rate at the second harmonic is high compared to the atomic decay rates. However, the cavity loss rate at the fundamental may still be slow compared to the atomic loss rateread more

The SLH framework for modeling quantum input-output networks
TL;DR: The SLH framework is reviewed, a powerful modeling framework for networked quantum systems that is naturally endowed with properties such as modularity and hierarchy, and the prospects for modeling integrated implementations of quantum input-output networks are discussed.

Nanocavity-based self-frequency conversion laser
TL;DR: The combined broadband quantum dot gain and small device footprint enables the monolithic integration of 26 different-color nanolasers within a micro-scale region, and provides a new platform for studying few-photon nonlinear optics, and for realizing full-color lasers on a single semiconductor chip.

Active versus passive squeezing by second-harmonic generation
TL;DR: In this article, the authors compared the characteristics of the second harmonic generation (SHG) with the passive and active SHG generation, and concluded that, although passive SHG is a practical source of squeezing, active second-harmonic generation is unlikely to be so in the foreseeable future.
