Noise 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 کاملMeasurement of the fourth cumulant of photo-assisted noise in a tunnel junction in the classical regime
The statistics of current fluctuations in a mesoscopic sample under irradiation has never been explored beyond the variance and third moment. We report the first measurement of the fourth cumulant of noise in a tunnel junction in the classical regime (i.e. kB T ≫ hf) in the presence of a d.c and microwave excitation, using two methods. First, we have investigated the correlation between the pow...
متن کاملON SIGNAL PROCESSINGBlind Intensity Estimation from Shot - Noise
| The estimation of the intensity function of an in-homogeneous Poisson process is considered when the observable data consists of sampled shot noise that results from passing the Poisson process through an unknown linear time-invariant system. The proposed method consists of rst estimating a histogram of the underlying point process. The estimated his-togram is used to construct a kernel estim...
متن کاملIntensity Correlations of a Noise Driven Diode Laser
We couple noise into the driving current of a laser diode to produce correlated light. We characterize the intensity correlations of the laser with two different techniques: two detector photon coincidence and analysis of the photocurrent from a single detector. The light exhibits bunching with a magnitude and characteristic time set by the bandwidth and amplitude of the noise modulating the la...
متن کاملIntensity noise correlations in a two-frequency VECSEL.
We present an experimental and theoretical study of the intensity noise correlation between the two orthogonally polarized modes in a dual frequency Vertical External Cavity Surface Emitting Laser (VECSEL). The dependence of the noise correlation spectra on the non-linear coupling between the two orthogonally polarized modes is put into evidence. Our results show that for small coupling the noi...
