Abstract

A constant-current driven semiconductor laser is one of the most powerful tools for generating amplitude squeezed lights.¹ Successful squeezing has been demonstrated in the strongly asymmetric cavity with low-reflectivity front mirror and high-reflectivity rear mirror.² The noise property of such lasers has been well described by the quantum Langevin equation which is suitable for symmetric high-Q cavity lasers or asymmetric cavity lasers with single-output coupling port. Recently, Goobar et al. observed the negative noise correlation between the facet intensities in a constant-current driven diode laser with cleaved facets. However, squeezing has not been observed since their experiment was carried out in the relatively low pump region.
