Raman-noise-induced noise-figure limit for χ(3) parametric amplifiers

Not Accessible

Your library or personal account may give you access

Abstract

The nonzero response time of the Kerr [χ3] nonlinearity determines the quantum-limited noise figure of χ3 parametric amplifiers. This nonzero response time of the nonlinearity requires coupling of the parametric amplification process to a molecular-vibration phonon bath, causing the addition of excess noise through Raman gain or loss at temperatures above 0 K. The effect of this excess noise on the noise figure can be surprisingly significant. We derive analytical expressions for this quantum-limited noise figure for phase-insensitive operation of a χ3 amplifier and show good agreement with published noise-figure measurements.
