Quantum-noise reduction in semiconductor lasers

Not Accessible

Your library or personal account may give you access

Abstract

A second-order correlation function approach is adopted to focus on the mechanism for generating amplitude-squeezed light in a semiconductor diode laser pumped with suppressed amplitude fluctuations. Second-order correlation functions between the electromagnetic field intensities and between the electromagnetic field intensities and the charge carrier numbers are calculated. Sub-Poissonian statistics and antibunching effects inside the laser cavity are analyzed; the analysis focuses on various quantities responsible for generating this state of the field. The influence of these quantities on the noise spectra of the detected field and conditions for quantum-noise reduction are considered.
