Noise beating in hybrid phase-sensitive amplifier systems.

چکیده
We investigate the effect of noise loading in a hybrid phase-sensitive amplifier system, analyzing the effect of noise beating between the signal and idler waves coupled in a parametric amplifier. Through analyzing input and output optical signal to noise ratios, we find that system performance of a phase-sensitive amplifier is 3 to 6 dB improved over a phase-insensitive amplifier, depending on the ratio of loaded noise power to that of vacuum fluctuations.

Optical signal to noise ratio improvement through unbalanced noise beating in phase-sensitive parametric amplifiers.
We investigate the beating of signal and idler waves, which have imbalanced signal to noise ratios, in a phase-sensitive parametric amplifier. Imbalanced signal to noise ratios are achieved in two ways; first by imbalanced noise loading; second by varying idler to signal input power ratio. In the case of imbalanced noise loading the phase-sensitive amplifier improved the signal to noise ratio f...

We describe the progress in fiber-based phase-sensitive parametric amplifiers in both frequency-degenerate and frequency-nondegenerate configurations. We discuss their applications for phase regeneration, as well as for lumped and distributed noiseless amplification. 2005 Optical Society of America OCIS codes: (060.2320) Fiber optics amplifiers and oscillators; (190.4410) Nonlinear optics, par...

In this paper, the spectral behavior of a two-cell phase conjugated mirror (PCM)with a two-pass Nd:YAG amplifier has been analyzed experimentally and theoretically. For this purpose, amplifier input intensity for the three different states of laser oscillator with one, two and three longitudinal modes have been investigated. The numerical model is based on 2-dimension equations of stokes back-s...
متن کاملSuppression of beating noise of narrow-linewidth erbium-doped fiber ring lasers by use of a semiconductor optical amplifier.
Beating noise in narrow-linewidth erbium-doped fiber ring lasers puts severe limitations on applications of the lasers. We demonstrate the suppression of beating noise in fiber ring lasers by using a semiconductor optical amplifier in the laser cavity, which acts as a high-pass filter. Two different ring structures are presented as examples to demonstrate this beating noise suppression.
متن کاملOptical Transmission Systems Based on Phase-Sensitive Amplifiers
The capacity and reach of today’s long-haul fiber optical communication systems is limited by amplifier noise and fiber nonlinearities. Conventional, phase-insensitive amplifiers (PIAs), have a quantum limited noise figure (NF) of 3 dB at high gain, meaning that with a shot-noise limited input signal the signal-to-noise ratio (SNR) is degraded by at least 3 dB. Phase-sensitive amplifiers (PSAs)...
