Abstract
We demonstrate 3.4-dB amplitude squeezing of a multiple quantum-well d istributed-feedback semiconductor laser operating at room temperature. The spontaneous-emission noise is eliminated by using a Michelson int erferometer, where the intensity noise due to spontaneous emission is cancelled by the intensity noise converted from the frequency noise. T he spectral density of the remaining noise is 3.4 dB below the shot-no ise level, which is limited by the differential quantum efficiency of the laser. (C) 1994 American Institute of Physics.
