Picosecond linear optical pulse shapers based on integrated Waveguide Bragg gratings.
Optics letters, 2008Co-Authors: L.m. Rivas, Roberto Morandotti, Marc Sorel, Michael J. Strain, David Duchesne, A. Carballar, José AzañaAbstract:We demonstrate a general linear pulse-shaping technique based on integrated III–V Bragg gratings (BGs). Such a technique allows for the synthesizing of complex waveforms with picosecond resolution using a compact Single-Waveguide design. This approach is experimentally demonstrated by fabricating and testing a series of integrated ultrafast optical pulse shapers based on BG geometries acting as time-domain code generators operating at 500 Gbits/s.

Optical pulse shaping for ultrahigh-bit-rate telecom applications based on III–V integrated Waveguide Bragg gratings
2008 34th European Conference on Optical Communication, 2008Co-Authors: L.m. Rivas, Roberto Morandotti, Marc Sorel, Michael J. Strain, David Duchesne, A. Carballar, José AzañaAbstract:We introduce a general linear pulse-shaping approach based on III-V integrated Single-Waveguide Bragg gratings for synthesizing arbitrary complex waveforms with (sub-)picosecond resolutions. Pulse code generators at 500 Gbps are demonstrated.

Stable soliton vs collapse dynamics of short laser pulses in nonlinear structures with intermediate dimensionality
2004Co-Authors: Dima Cheskis, Shimshon Bar-ad, Roberto Morandotti, J.s. Aitchison, Hagai S. Eisenberg, Yaron Silberberg, Duncan M. RossAbstract:We investigate the propagation of short laser pulses in arrays of coupled nonlinear Waveguides. In the experiment we inject intense 60fs pulses into planar silica Waveguide arrays, with the laser tuned to the anomalous dispersion regime. Depending on the excitation conditions, either collapse dynamics is observed, or trapping of the pulse in a Single Waveguide. The collapse dynamics in these intermediate ∗ Presented at Russian-Israeli Conference Frontiers in Condensed Matter Physics.

Strong spatiotemporal localization in a silica nonlinear Waveguide array.
Physical review letters, 2003Co-Authors: Dima Cheskis, Shimshon Bar-ad, Roberto Morandotti, J.s. Aitchison, Hagai S. Eisenberg, Yaron Silberberg, Duncan M. RossAbstract:We investigate the propagation of short, intense laser pulses in arrays of coupled silica Waveguides, in the anomalous dispersion regime. The nonlinearity induces trapping of the pulse in a Single Waveguide, over a wide range of input parameters. A sharp transition is observed for Single Waveguide excitation, from strong diffraction at low powers to strong localization at high powers.

Nonlinearly induced escape from a defect state in Waveguide arrays
Applied Physics Letters, 1999Co-Authors: Ulf Peschel, Roberto Morandotti, J.s. Aitchison, Hagai S. Eisenberg, Yaron SilberbergAbstract:We experimentally investigate the linear and nonlinear optical properties of a nonuniform Waveguide array. By reducing the width of a Single Waveguide, we decrease its effective index and induce waveguiding along the defect. Due to the positive nonlinearity, the index difference is reduced for increasing power levels with the result that the field escapes. Waveguiding is suppressed by the action of the nonlinearity.
