Abstract

Nonclassical multiphoton states of light with squeezed quantum fluctuations are in demand for various ultrahigh-accuracy measurements. In this study, we propose to use fiber of bismuth-modified zinc-tellurite glass with high Kerr nonlinearity to squeeze quantum noise of optical signals. We experimentally fabricated such fiber and, using numerical simulation of the nonlinear evolution of cw laser signal taking into account fiber characteristics for optimum parameters, theoretically demonstrated noise squeezing better than -15 dB.
