Multi-channel phase squeezing in a PPLN-PPLN PSA

Abstract

We investigate phase squeezing of up to four signal channels in a non-degenerate phase-sensitive amplifier constructed from periodically-poled-lithium-niobate waveguides and observe that additional channels have little impact the phase squeezing performance.

Phase-squeezing properties of non-degenerate PSAs using PPLN waveguides

Benjamin James Puttnam, Dániel Mazroa, Satoshi Shinada +1 more

We investigate the phase squeezing characteristics of non-degenerate phase-sensitive-amplifiers (PSAs) based on periodically-poled-lithium-niobate (PPLN) waveguides. We implement two PSA configurations with phase insensitive idler generation performed in both highly-non-linear-fiber (HNLF) and PPLN waveguides. In both cases we demonstrate regeneration of a noisy BPSK signal, despite net signal attenuation in the phase sensitive PPLN, and show that the level of phase squeezing varies with the phase sensitive dynamic range (PSDR). We observe that weak idler generation in the PPLN limits the achievable PSDR and that use of HNLF for idler generation leads to the largest PSDR. However, in phase regeneration measurements we observe that the pump phase modulation, required to overcome stimulated Brillouin scattering, adds significant amplitude noise, which increases with the PSDR.

Investigation of an All-Optical Black-Box PPLN-PPLN BPSK Phase Regenerator

A. Szabo, Benjamin James Puttnam, Dániel Mazroa +2 more

We investigate the phase squeezing performance of an all-optical black-box binary phase-shift keyed phase regenerator constructed from periodically-poled lithium-niobate (PPLN) waveguides. Phase regeneration is performed with different levels of phase noise and constant amplitude noise added to the phase modulated input. We experimentally show that, for moderate phase noise, unwanted phase-to-amplitude noise conversion can be minimized without degradation of the phase squeezing performance, by controlling the signal-to-pump power ratio at the input to the PPLN-based phase-sensitive regenerator.
