A Cost-Benefit Analysis on Modulation Formats for 40-Gb/s Optical Communication Systems
(TAYLOR & FRANCIS INC, 2011)
This article discusses possible approaches for optical network capacity upgrade by considering the use of different modulation formats at 40 Gb/s. First, a performance evaluation is carried out regarding tolerance to three ...
Z-scan and spatial self-phase modulation of a Gaussian beam in a thin nonlocal nonlinear media
(Journal of Optics, 2011)
Measurement of phase and amplitude modulations in Sb-Based Films
(2009-11-23)
In this work we studied the changes of the optical constants of films in the binary system Sb2O3-Sb2S3 induced by light in the VIS-UV. The measurements were performed before and after homogeneous irradiation of the films ...

Extending the high-order harmonic generation cutoff by means of self-phase-modulated chirped pulses
(IOP Publishing, 2016-11)
In this letter we propose a complementary approach to extend the cutoff in high-order harmonic generation (HHG) spectra beyond the well established limits. Inspired by techniques normally used in the compression of ultrashort ...
Analysis and measurement of the non-linear refractive index of SiOxNy using pedestal waveguides
(Ieee, 2019-01-01)
In this work, the non-linear refractive index (n(2)) of silicon oxynitride (SiOxNy) is determined, obtaining a value for this material of n(2) = 2.11x10(-19) m(2)/W. The results demonstrate that this material has interesting ...
Analysis and measurement of the non-linear refractive index of SiOx Ny using pedestal waveguides

In this work, the non-linear refractive index (n2) of silicon oxynitride (SiOx Ny) is determined, obtaining a value for this material of n2 = 2.11×10-19 m2/W. The results demonstrate that this material has interesting ...
Phase modulation in two-wave mixing for dynamically recorded gratings in photorefractive materials

Perpendicularly self-oriented and shape-controlled L1(0)-FePt nanorods directly synthesized by a temperature-modulated process
(TSINGHUA UNIV PRESS, 2011)
The synthesis and self-assembly of tetragonal phase-containing L1(0)-Fe(55)Pt(45) nanorods with high coercive field is described. The experimental procedure resulted in a tetragonal/cubic phase ratio close to 1:1 for the ...
