Title: Absorption-induced optical bistability and dissipative solitons in a BEC interferometer

Abstract

A model of the absorption-induced nonlinear response of an atomic Bose-Einstein condensate driven by a weak resonant laser beam is presented. The model takes into account the slow BEC decay due to spontaneous emission and magnetic-trap loss by binary collisions, as well as compensation of the decay by injection of ground-state atoms into the trap. It is shown that the nonlinear response is much stronger than in other nonlinear optical media. For a BEC interferometer driven by a monochromatic beam, the threshold intensity for hysteretic switching is found, and dissipative spatial solitons are demonstrated.

  • An analysis of the dependence of radiation transmitted through a nonlinear Fabry-Perot interferometer on the incident flux intensity is useful for considering a new class of optical signal processing-bistable elements. The authors studied the peculiarities of optical bistability caused by mirror symmetry of the Gaussian emmission and absorption coefficients. Calculations were made on the assumption that the interferometer was of high quality. The results show that Stoke's displacement of the emission band has a significant effect on the transmission characteristics of a Fabry-Perot interferometer, and they illustrate preferred operation at offset frequency tuning towards the short-wave region of the spectrum.
  • The problem of nonlinear scattering of optical pulses in a dense three-level atomic medium with continuous pumping is considered with allowance for the local field effects. The physical requirements on the parameters of the medium and field are formulated, and the ranges of these parameters for which stationary solitons are effectively formed in the model of a quartz waveguide doped with {sup 87}Rb atoms are determined using variational methods. It is found that disregarding the local field in this model results in violation of soliton stability in the predicted parameter range.
  • We report results of a systematic analysis of the stability of dissipative optical solitons, with intrinsic vorticity S=0 and 1, in the three-dimensional complex Ginzburg-Landau equation with the cubic-quintic nonlinearity, which is a model of a dispersive optical medium with saturable self-focusing nonlinearity and bandwidth-limited nonlinear gain. The stability is investigated by means of computation of the instability growth rate for eigenmodes of small perturbations, and the results are verified against direct numerical simulations. We conclude that the presence of diffusivity in the transverse plane is necessary for the stability of vortex solitons (with S=1) against azimuthal perturbations, while zero-vorticitymore » solitons may be stable in the absence of the diffusivity. On the other hand, the solitons with S=0 and S=1 have their stability regions at both anomalous and normal group-velocity dispersion, which is important to the experimental implementation. At values of the nonlinear gain above their existence region, the solitons either develop persistent intrinsic pulsations, or start expansion in the longitudinal direction, keeping their structure in the transverse plane.« less
  • We present a method for the study of quantum fluctuations of dissipative structures forming in nonlinear optical cavities, which we illustrate in the case of a degenerate, type I optical parametric oscillator. The method consists in (i) taking into account explicitly, through a collective variable description, the drift of the dissipative structure caused by the quantum noise, and (ii) expanding the remaining--internal--fluctuations in the biorthonormal basis associated to the linear operator governing the evolution of fluctuations in the linearized Langevin equations. We obtain general expressions for the squeezing and intensity fluctuations spectra. Then we theoretically study the squeezing properties ofmore » a special dissipative structure, namely, the bright cavity soliton. After reviewing our previous result that in the linear approximation there is a perfectly squeezed mode irrespective of the values of the system parameters, we study which are the better squeezed modes at the different bifurcations that the cavity soliton can suffer, as well as the squeezing level attainable when the homodyne detection is made with a plane-wave local oscillator field. In this last case, the squeezing level is quite large in most of the existence domain of the cavity soliton. We then take into account the effect of the detector size and find that, in general, squeezing degrades as the detector is made smaller, except for detector sizes around the cavity soliton size, in which case there is an interesting deviation from the general trend.« less
  • Dynamics and stability of solitons in two-dimensional (2D) Bose-Einstein condensates (BEC), with one-dimensional (1D) conservative plus dissipative nonlinear optical lattices, are investigated. In the case of focusing media (with attractive atomic systems), the collapse of the wave packet is arrested by the dissipative periodic nonlinearity. The adiabatic variation of the background scattering length leads to metastable matter-wave solitons. When the atom feeding mechanism is used, a dissipative soliton can exist in focusing 2D media with 1D periodic nonlinearity. In the defocusing media (repulsive BEC case) with harmonic trap in one direction and nonlinear optical lattice in the other direction, themore » stable soliton can exist. Variational approach simulations are confirmed by full numerical results for the 2D Gross-Pitaevskii equation.« less
