Signal-to-Noise Ratio in Raman Active Fiber Delay Lines Application to Recirculating

E. Desurvire, Moshe Tur, H. J. Shaw

Published Jan 1, 1986• 0 citations

Abstract

An analysis of photon count statistics of noise in Raman fiber amplifiers and passive optical components is presented. The re- sults are used for evaluating the output signal-to-noise ratio (SNR) of Raman active recirculating delay lines. It is found that the quadratic dependence of the noise on the number of recirculations causes the SNR to decay with increasing optical delays. Ultimate system perfor- mance capabilities, as determined by the SNR quantum limit, are dis- cussed.

Optimum noise performance of optical amplifiers

H. A. Haus

The concept of noise figure F and noise measure M applicable to radio frequency and microwave amplifiers is reviewed and extended to cover optical amplifiers. Two noise figures are defined in the optical regime: one gives the ASE output, while the other gives the ratio of signal-to-noise ratios at the input and output. In the quantum regime, the lower limit on these optimum values is set by a generalization of Heisenberg's uncertainty relation. A Raman back-pumped fiber link with post-amplification with an erbium-doped fiber amplifier is used to illustrate the use of noise measure.

Output moments and photon statistics in fiber raman amplification

R. W. Davies, Paul Melman, Walter Nelson +2 more

The problem of output moments, photon statistics, and signal-to-noise ratio in fiber Raman amplification is considered using a master equation approach, including absorption in the signal and pump modes. In the parametric approximation for the pump, results are obtained for the output moments which can be cast in a general form derived by Loudon and Shepherd [23] for phase-insensitive quantum amplifiers and attenuators. Beyond the parametric approximation, it is shown that the output moments of the signal may be obtained through iteration from lower order moments in an approximation where signal-pump correlation is ignored. Comparison with other work is discussed.

An optical amplifier followed by a bistable element has been statistically analyzed before. In this manuscript, output noise analysis represents, then signal to noise ratios (SNR) are calculated either for input or output. It will be shown that noise reduction, can be achieved by a proper selection of parameters.

Photon statistics of a single mode of spontaneous Raman scattering in a distributed Raman amplifier

Paul L. Voss, Yikai Su, Prem Kumar

Experimental measurement of spontaneous noise statistics from a distributed Raman amplifier has been achieved with single-mode and single-photon resolution. The results agree with quantum theoretical predictions of a Bose-Einstein probability distribution. Distributed Raman amplification is becoming increasingly important in today's optical communication systems. It improves the optical signal-to-noise ratio by providing optical gain inside the transmission fiber.

Optical signal-to-noise ratio measurement by optical homodyne tomography

Paolo Martelli, Silvia Maria Pietralunga, Leonardo Ranzani +2 more

An all-fiber optical homodyne tomography setup is introduced that measures the optical signal-to-noise ratio through reconstruction of the photon statistics. The scheme described has been conceived for applications to optical communications. In particular, the signal-to-noise ratio has been evaluated at lambda= 1.55 microm as a function of the received power. From the experimental data, in the case of optically amplified signals, the amplifier noise figure can be estimated.

Distortion, Noise and Delay study for Wavelength-Conversion and Dispersion Based Slow-Light System

Ravi Pant, Michael D. Stenner, Mark Allen Neifeld

For wavelength-conversion dispersion based slow-light system, large gain required for amplifying the incoming pulses increases delay at the expense of amplifier noise. We present the distortion, signal-to-noise ratio (SNR) and delay tradeoff in these systems.
