Nonlinear fiber system for shot-noise limited intensity noise suppression and amplification
نویسندگان
چکیده
We propose a nonlinear fiber system for shot-noise limited, all-optical intensity-noise reduction and signal amplification. The mechanism is based on the accumulation of different phase shifts between orthogonal polarization modes in polarization-maintaining amplifier combination with an implemented sinusoidal transmission-function. resulting correlation input intensity-fluctuations transmission enables tunable intensity noise pulse train. In experiment, spectral density mode-locked oscillator suppressed by up to ~20 dB theoretical limit measurement at -151.3 dBc/Hz simultaneous amplification 13.5dB.

Shot-noise suppression at two-dimensional hopping
We have used Monte Carlo simulation to calculate the shot-noise intensity SI(v) at ~two-dimensional! hopping using two models: a slanted lattice of localized sites with equal energies and a set of localized sites with random positions and energies. For wide samples we have found a similar dependence of the Fano factor F[SI(0)/2eI on the sample length L: F}L 2a where a50.8560.02 and a50.8560.07 ...
متن کاملShot noise suppression at one-dimensional hopping
We have carried out a preliminary analysis of shot noise at hopping, focusing on uniform one-dimensional ~1D! arrays of sites separated by N tunnel barriers. The results show that at low temperatures the low-frequency density of the shot noise varies from 1/N to 1 of the Schottky value, depending on the geometry, electron density, and Coulomb interaction strength. An interesting feature is v de...
متن کاملNoise Intensity-Intensity Correlations and the Fourth Cumulant of Photo-assisted Shot Noise
We report the measurement of the fourth cumulant of current fluctuations in a tunnel junction under both dc and ac (microwave) excitation. This probes the non-Gaussian character of photo-assisted shot noise. Our measurement reveals the existence of correlations between noise power measured at two different frequencies, which corresponds to two-mode intensity correlations in optics. We observe p...
متن کاملJohnson Noise and Shot Noise
Two types of electrical noise fundamental to any circuit and their relation to fundamental constants are investigated. Johnson noise of a controlled-gain system is measured across different resistances and temperatures, leading to a calculation of the Boltzmann constant k = (1.48± .07)×10−23J/K and absolute zero T0 = −(270±30) ◦C. The shot noise of a variable-current system is measured, leading...
متن کاملOn the nonlinear modeling of shot noise.
We introduced a nonlinear shot-noise model, a natural generalization of the "classic" shot-noise model, which differs markedly from the existing linear shot-noise models. This model produces a wide spectrum of stationary noise processes. Because of its intrinsic nonlinearity, the model's resulting noise processes are capable of displaying a rich variety of both amplitudal and temporal statistic...
