Abstract

Applications of nonclassical states of the electromagnetic field, because of the inherent low noise properties of such states,¹ have motivated much of the recent progress in the development of squeezed light sources. Early success generating quadrature squeezed light led to its rapid application to problems in interferometry, spectroscopy, and modulation,² which serve as clear confirmation of the nonclassical benefits of squeezed light. More recently, semiconductor sources, which feature photon-number squeezed output, compactness, and low cost, have been utilized in practical demonstrations.³
