Modeling of the refractive index profile of a femtosecondwritten waveguide in LiNbO3
Damian A. Presti, Valentın Guarepi, Fabian Videla +1
Femtosecond laser pulse systems allows to modify in a precise and permanent way the optical properties of atransparent materials. This process enables the direct writing of guiding…
Effective super-bandwidth in laser pulses
Enrique G. Neyra, Demian A. Biasetti, Pablo Vaveliuk +4
We present here a theoretical analysis of the interaction between an ideal two-level quantum system and a super-oscillatory pulse, like the one proposed and successfully synthesize…
Simple interferometric setup enabling sub-Fourier-scale ultra-short laser pulses
Enrique G. Neyra, Gustavo A. Torchia, Pablo Vaveliuk +1
In this work, we have developed a method to generate ultra-short pulses below the Fourier limit, extending the concept previously worked in reference 1 for generating sub-diffracti…
Small MMI with simplified coherent coupling branches used to develop a lower footprint power splitter on SOI platform
R. Peyton, J. Martinez Valdivieso, D. Presti +1
In this paper, we introduce a new approach to fabricate under the Silicon on Insulator (SOI) platform a 1x2 power splitter and scale it to 1xN system device from the proposed model…
Phenomenological studies of femtosecond laser ablation on optical thin films for integrated photonics
R. Peyton, V. Guarepi, G. A. Torchia
In this work, for the first time of our knowledge, we present a well-supported procedure to fabricate ridge optical waveguides onto thin films of PLZT by femtosecond laser ablation…
High-order harmonic generation driven by inhomogeneous plasmonics fields spatially bounded: influence on the cut-off law
E. Neyra, F. Videla, M. F. Ciappina +4
We study high-order harmonic generation (HHG) in model atoms driven by plasmonic-enhanced fields. These fields result from the illumination of plasmonic nanostructures by few-cycle…
High-order harmonic generation driven by chirped laser pulses induced by linear and non linear phenomena
E Neyra, F Videla, J A Pérez-Hernández +3
We present a theoretical study of high-order harmonic generation (HHG) driven by ultrashort optical pulses with different kind of chirps. The goal of the present work is perform a…
