Summary form only given. Recently B.A. Malomed theoretically predicted the existence of bound states of solitons in the dissipatively perturbed nonlinear Schrodinger equation. In this talk we report on the first experimental observation of bound soliton states in a passively mode locked fiber soliton laser. Multiple soliton operation is a generic feature of passively mode-locked fiber soliton lasers...
Summary form only given. The collision of optical pulses in a fiber is a promising concept for quantum-nondemolition (QND) measurements of the photon-number using the Kerr effect induced cross-phase modulation (XPM). Spectral filtering of solitons produced strong photon-number noise reduction below shot noise in direct detection. We present a novel QND experiment based on the XPM-induced frequency...
Summary form only given. In order to manufacture a modelocked, pulsed atom laser, we suggest the idea of making use of the atom-atom repulsion in a BEC to form a toroidal soliton which can then form a reproducible, coherent waveform. The relevant solitons have the form of a kink, or phase-singularity in the nonlinear Schrodinger equation. We suppose that the atoms are all trapped in a deep, toroidal...
Summary form only given. There has always been a close link in optically nonlinear media between solitons and high power beam break-up, i.e., modulational instability (MI). The classical example are temporal solitons, and the break-up of CW beams into a periodic pattern of pulses in fibers. Similarly for spatial solitons which have a finite spatial extent, very wide beams break up into periodic filaments...
