Dejonckheere A, Duport F, Smerieri A, Fang L, Oudar JL, Haelterman M, Massar S.
PMID: 24921786
Opt Express. 2014 May 05;22(9):10868-81. doi: 10.1364/OE.22.010868.

Reservoir computing is a new bio-inspired computation paradigm. It exploits a dynamical system driven by a time-dependent input to carry out computation. For efficient information processing, only a few parameters of the reservoir needs to be tuned, which makes...

Dispersion-induced dynamical transition in parametric solitary waves.

Physical review letters

Picozzi A, Haelterman M.
PMID: 10991048
Phys Rev Lett. 2000 Jun 19;84(25):5760-3. doi: 10.1103/PhysRevLett.84.5760.

We investigate the influence of dispersion on parametric solitary waves. We show that dispersion is responsible for a transition towards a new type of dynamical solitary wave characterized by the presence of traveling phase defect arrays within their envelopes....

Self-induced modulational instability laser revisited: normal dispersion and dark-pulse train generation.

Optics letters

Sylvestre T, Coen S, Emplit P, Haelterman M.
PMID: 18007838
Opt Lett. 2002 Apr 01;27(7):482-4. doi: 10.1364/ol.27.000482.

We study theoretically and experimentally the so-called self-induced modulational instability laser and show that the passive mode-locking mechanism that is at play in this laser relies on a dissipative four-wave mixing process that leads to generation of a dark-pulse...

Experimental error filtration for quantum communication over highly noisy channels.

Physical review letters

Lamoureux LP, Brainis E, Cerf NJ, Emplit P, Haelterman M, Massar S.
PMID: 16090449
Phys Rev Lett. 2005 Jun 17;94(23):230501. doi: 10.1103/PhysRevLett.94.230501. Epub 2005 Jun 13.

Error filtration is a method for encoding the quantum state of a single particle into a higher dimensional Hilbert space in such a way that it becomes less sensitive to noise. We have realized a fiber optics demonstration of...

Observation of resonance soliton trapping due to a photoinduced gap in wave number.

Physical review letters

Van Simaeys G, Coen S, Haelterman M, Trillo S.
PMID: 15245226
Phys Rev Lett. 2004 Jun 04;92(22):223902. doi: 10.1103/PhysRevLett.92.223902. Epub 2004 Jun 02.

We investigate the nonlinear propagation of two forward propagating modes coupled by a resonant traveling-wave grating, which is photoinduced by illuminating an optical fiber with a beat signal. This interaction, representative of systems whose dispersion relation K=K(Omega) exhibits a...

Dark-soliton jitter in amplified optical transmission systems.

Optics letters

Hamaide JP, Emplit P, Haelterman M.
PMID: 19777037
Opt Lett. 1991 Oct 15;16(20):1578-80. doi: 10.1364/ol.16.001578.

The transmission of dark solitons in ultralong transmission systems with optical amplification is numerically investigated. We show that amplifier noise is responsible for a random frequency shift with a resulting time jitter radical2 times lower than that observed for...

Observation of modulational instability induced by velocity-matched cross-phase modulation in a normally dispersive bimodal fiber.

Optics letters

Millot G, Pitois S, Dinda PT, Haelterman M.
PMID: 18188335
Opt Lett. 1997 Nov 15;22(22):1686-8. doi: 10.1364/ol.22.001686.

We demonstrate experimentally the existence of cross-phase-modulation-induced modulational instability in the absence of group-velocity mismatch between the interacting nonlinear dispersive waves. The experiment is performed by means of a normally dispersive isotropic bimodal fiber. The group-velocity mismatch between the...

Multiple soliton bound states and symmetry breaking in quadratic media.

Optics letters

Haelterman M, Trillo S, Ferro P.
PMID: 18183110
Opt Lett. 1997 Jan 15;22(2):84-6. doi: 10.1364/ol.22.000084.

We present a study of the dynamics of multiple soliton bound states in diffractive media with second-order nonlinearity. A numerical stability analysis of these bound states reveals that wave propagation in quadratic materials exhibits spatial symmetry-breaking instabilities.

Fast self-pulsing through nonlinear incoherent feedback.

Optics letters

Kockaert P, Cambournac C, Haelterman M, Kozyreff G, Erneux T.
PMID: 16496898
Opt Lett. 2006 Feb 15;31(4):495-7. doi: 10.1364/ol.31.000495.

We consider a double-pass ring cavity with nonlinear incoherent optical feedback and analyze its response when it is driven by a continuous laser beam. This particular cavity is equivalent, in the temporal domain, to a simple spatial-pattern-generating system made...

Gordon-Haus effect on dark solitons.

Optics letters

Kivshar YS, Haelterman M, Emplit P, Hamaide JP.
PMID: 19829529
Opt Lett. 1994 Jan 01;19(1):19-21. doi: 10.1364/ol.19.000019.

The theory of the Gordon-Haus effect with application to dark solitons is presented. It is proved analytically that a random frequency shift of a fundamental dark soliton results in a time jitter radical2 times lower than that for bright...

Experimental demonstration of the oscillatory snake instability of the bright soliton of the (2+1)D hyperbolic nonlinear Schrödinger equation.

Physical review letters

Gorza SP, Deconinck B, Emplit P, Trogdon T, Haelterman M.
PMID: 21405625
Phys Rev Lett. 2011 Mar 04;106(9):094101. doi: 10.1103/PhysRevLett.106.094101. Epub 2011 Mar 01.

The transition between the standard snake instability of bright solitons of the hyperbolic nonlinear Schrödinger equation and the recently theoretically predicted oscillatory snake instability is experimentally demonstrated. The existence of this transition is proven on the basis of spatiotemporal...
