Journal ArticleDOI
Femtosecond writing of active optical waveguides with astigmatically shaped beams
Roberto Osellame,Stefano Taccheo,Marco Marangoni,Roberta Ramponi,Paolo Laporta,Dario Polli,Sandro De Silvestri,Giulio Cerullo +7 more
TL;DR: In this article, an approach for the fabrication of optical waveguides by focused low-repetition-rate femtosecond laser pulses is described. But the main limitation of this approach is the strong asymmetry of the waveguide profile.
Journal ArticleDOI
Observation of dynamic localization in periodically curved waveguide arrays.
Stefano Longhi,Marco Marangoni,Mirko Lobino,Roberta Ramponi,P. Laporta,Elena Cianci,Vittorio Foglietti +6 more
TL;DR: The theoretical condition for DL in a sinusoidal field is experimentally demonstrated and the optical analog of DL for electrons in periodic potentials subjected to ac electric fields as originally proposed by Dunlap and Kenkre is reported on.
Journal ArticleDOI
Femtosecond micromachining of symmetric waveguides at 1.5 microm by astigmatic beam focusing.
Giulio Cerullo,Roberto Osellame,Stefano Taccheo,Marco Marangoni,Dario Polli,Roberta Ramponi,Paolo Laporta,S. De Silvestri +7 more
TL;DR: A new spatial beam-shaping approach for fabrication of waveguides with a circular transverse profile by femtosecond laser pulses, using an astigmatic beam and controlling both beam waist and focal position in the tangential and sagittal planes is reported.
Journal ArticleDOI
Single-cycle multiterahertz transients with peak fields above 10 MV/cm.
F. Junginger,Alexander Sell,Olaf Schubert,Bernhard Mayer,Daniele Brida,Marco Marangoni,Giulio Cerullo,Alfred Leitenstorfer,Rupert Huber +8 more
TL;DR: Phase-locked single-cycle transients with frequency components between 1 and 60THz and peak fields of up to 12MV/cm are generated as the idler wave of a parametric amplifier to achieve broadband conversion in GaSe nonlinear crystals and the group velocities of signal and idler components are matched.
Journal ArticleDOI
Few-optical-cycle pulses tunable from the visible to the mid-infrared by optical parametric amplifiers
Daniele Brida,Cristian Manzoni,Giovanni Cirmi,Marco Marangoni,Stefano Bonora,Paolo Villoresi,S. De Silvestri,Giulio Cerullo +7 more
TL;DR: In this paper, the authors review recent work on the development of ultra-broadband OPAs and experimentally demonstrate pulses with durations approaching the single-cycle limit and almost continuous tunability from the visible to the mid IR.
