Abstract

Analysis of photonic noise in wide-aperture nonlinear interferometer excited by external radiation is presented. The possibility of spatio-temporal squeezed states generation and of effective noise suppression in a definite range of temporal and spatial frequencies is demonstrated.

Squeezing in Wide-Aperture Nonlinear Interferometer: Transverse Effects

Aleksandr V. Belinsky, N.N. Rosanov

Fluctuations of radiation and of photodetector current present a fundamental limit for capabilities of parallel optical processing. In this connection it seems perspective to use the light squeezed states to depress photon noise of optical images. In this report we consider a possibility of generation of sufficiently wide (multi-mode) beams of sub-Poisson light transmitting coherent radiation through wide-aperture nonlinear interferometer.

Sub-Poissonian light by spatial soliton filtering

Antonio Mecozzi, Prem Kumar

We show that spatial filtering of Kerr spatial solitons produces sub-Poissonian (amplitude-squeezed) light. Filtering can be performed in either the near field or the far field of the spatial soliton at the output of the Kerr medium. Up to 6.5 dB of squeezing is predicted by placing a square aperture of 82% transmittance in the far field.

Can photon noise be reduced ?

Serge Reynaud, A. Heidmann

The sensitivity of the interferometric methods for detection of gravitational waves is limited at the moment by photon noise. This noise can theoretically be reduced by entering in one input part of the interferometer a field in a particular quantum state, the so called squeezed state. A wide variety of non-linear processes, such as the degenerate four wave mixing, can realize the transformation of coherent states of the field into squeezed states. We show that the photon noise reduction is very sensitive to the spatial and temporal coherence properties of the squeezed field, and that photon noise is not appreciably reduced with incoherent sources of squeezed field.

Sub-Poisson source of radiation with strong suppression of quantum fluctuations of the intensity

А. В. Белинский, Anatolii S Chirkin

An analysis is made of new possibilities of formation of a sufficiently strong radiation source with a sub-Poisson photon statistics. A nonlinear interferometer, excited by radiation from a degenerate parametric frequency converter, is proposed and analyzed in detail. In such a nonlinear interferometer the transformation due to phase modulation can not only suppress almost completely the classical intensity fluctuations, but also reduce greatly the quantum fluctuations. It is shown that the Fano factor (ratio of the photon number variance to the average number of photons) can under optimal conditions have a value of the order of 0.1.

Single-mode amplitude squeezing in a semiconductor laser at 780 nm

Ya. A. Fofanov, I. V. Sokolov

The problem of the creation of a sub-Poissonian radiation source on the basis of a semiconductor laser with an external cavity is considered, which operates, from the viewpoint of quantum optics, in the single-mode regime. The conditions of the generation of sub-Poissonian radiation, under which the whole set of sub-threshold modes, including the nearest modes of the external (long) cavity, is completely suppressed at room temperature, were experimentally revealed and theoretically studied. Single-frequency low-noise lasing is of interest not only for the creation of nonclassical light sources, but also for sensitive spectroscopic applications in the classical domain.

Sub-Poissonian light from a laser with an injected signal

Márcia T. Fontenelle, L. Davidovich

We show that the injection of an external field in a laser helps to improve amplitude squeezing and sub-Poissonian light generation close to threshold, but spoils quantum noise reduction for very high pumping rates. A general nonlinear theory is developed for the resonant case (no detunings), without any assumption on the relative magnitudes of field and atomic decay constants, thus encompassing a large class of lasers. Several possible pumping schemes are accommodated, ranging from regular to Poissonian. We carry out a detailed stability analysis of the general equations of motion, relating it to the noise-reduction problem. Both the photon-number variance inside the cavity and the homodyne spectra of the output are discussed.
