Abstract

Squeezed light sources are crucial components of emerging quantum technologies for computing, communications, and measurement. The direct generation of squeezed light inside optical fibre is of particular interest due to minimal material loss, desirable mode properties and compatibility with long-distance optical networks. Squeezing of bright coherent-state laser pulses in fibre is regularly achieved via the Kerr effect, but this is not readily extensible to the continuous-wave (CW) and null-mean field regimes, and the maximum measurable squeezing is degraded by various noise processes around the common pump/signal wavelength [1].
