QUANTUM-NOISE REDUCTION IN SEMICONDUCTOR-LASERS

A second-order correlation function approach is adopted to focus on th e mechanism for generating amplitude-squeezed light in a semiconductor diode laser pumped with suppressed amplitude fluctuations. Second-ord er correlation functions between the electromagnetic field intensities and between the electromagnetic field intensities and the charge carr ier 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 detect ed field and conditions for quantum-noise reduction are considered. (C ) 1996 Optical Society of America
