An optical fiber with a high Kerr nonlinearity coefficient is proposed and produced from a bismuth-modified tellurite glass for creation of nonclassical multiphoton states of light. Specifically, we propose to use those fibers to squeeze the quantum fluctuations of one of the quadratures of light in the 20 W signal significantly below -10 dB compared to the standard quantum noise limit, which is important for various practical applications. Using numerical modeling based on stochastic nonlinear Schrodinger equation, we demonstrate noise squeezing stronger than -16 dB for lengths of tellurite fiber 6-14 m, while squeezing of -14 dB is expected in silica fibers for lengths of 120-300 m. Analytical formulas were used to analyse the physical factors which limit the squeezing achievable.
