Classical and nonclassical properties of optical solitons propagating in tellurite fibers

Abstract

Here we study classical and nonclassical properties of optical solitons propagating in tellurite suspended-core fibers (SCF) based on the generalized nonlinear Schrodinger equation with Kerr and Raman nonlinearities and stochastic noise terms. It is shown that for SCFs nonlinear Kerr coefficients can be up to 3 orders of magnitude larger than the nonlinear coefficient of standard silica fibers and absolute values of anomalous dispersion can be up to 2 orders of magnitude larger than for silica fibers. Using ~100-fs pulses can lead to effective soliton self-frequency shift, but using pulses with ps durations can lead to suppressing Raman effects and observing quantum-squeezing effects.
