In prior setups involving Kerr-squeezed light, the role of the interferometer was merely to characterize the noise pattern. The lack of such a demonstration was largely due to the cumbersome tilting of the squeezed ellipse in phase space. Here, we present the first experimental observation of phase-sensitivity enhancement in an interferometer using Kerr squeezing.engAtribución 3.0 Españahttps://creativecommons.org/licenses/by/3.0/es/journal articlehttp://dx.doi.org/10.1515/nanoph-2023-0032https://www.degruyter.comopen access535NoiseLimitFluctuationsGenerationReductionSolitonsVortexStatesÓptica (Física)2209.19 Óptica Física
