Photon-number squeezing in the normal-dispersion regime

Abstract

We experimentally demonstrate the generation of amplitude-squeezed light in the normal-dispersion regime and measure by direct detection 1.7 +/- 0.1 dB (33%) and, with correction for linear losses, 2.5 +/- 0.2 dB (47%) of noise reduction below the shot-noise level. The dependence of the noise behavior on dispersion is investigated both experimentally and theoretically. (C) 1999 Optical Society of America.
