Theoretical analysis of quantum noise suppression of light in bismuth-modified tellurite fibers

Optical sources of squeezed quantum light are required for various ultraprecise measurements. For fiber-based Kerr squeezing technologies, silica fibers are widely used. Here an alternative fiber made of highly-nonlinear bismuth-modified tellurite glass is considered. We performed quantum dynamical simulations and analytical estimations and showed the possibility of attaining high quantum noise suppression up to -15 dB.
