Using coherent nonlinear optical spectroscopy below the band edge of a GaAs/Al0.3Ga1-0.3As multiple quantum well, photon-number squeezed light generated by a quantum-well laser is used to resolve the exciton resonances and the Urbach tail with detection sensitivity below the semiclassical shot-noise limit. The effect of polarization-dependent noise in the nonclassical probe field is also investigated.
