High-impedance pump noise suppression was used to generate amplitude squeezing in an index-guided quantum-well laser. Light exhibiting photon-number noise 1.4 dB below the shot-noise limit was observed, and the corresponding polarization properties were examined. Close-coupled laser-detector measurements made with an unsaturated detector revealed 2.9 dB of squeezing.
