Abstract

We achieved degenerate phase-sensitive amplification with the gain of over 30 dB under a CW condition using a periodically poled LiNbO3 waveguide module, which uses second- harmonic pump light to directly amplify the signal.

Phase sensitive amplification with noise figure below the 3 dB quantum limit using CW pumped PPLN waveguide

Masaki Asobe, Takeshi Umeki, Osamu Tadanaga

The noise figure (NF) of a phase sensitive amplifier (PSA) based on a periodically poled LiNbO3 (PPLN) waveguide was evaluated in the optical and electrical domains. Phase sensitive amplification was realized using degenerate parametric amplification in the PPLN waveguide, which was pumped by the second harmonic frequency of the signal. Second harmonic pumping enables direct observation of the intrinsic amplified spontaneous emission (ASE), which determined the NF of the PSA. An NF below the 3 dB quantum limit was obtained by observing the intrinsic ASE. The low NF was also confirmed via the noise floor measurement of a cascaded PSA and erbium doped fiber amplifier in the electrical domain. The PSA was used as a preamplifier for detecting a 40 Gbit/s phase shift keying signal. The low noise characteristics were confirmed by the improved sensitivity.
