Experimental investigation of the optical Kerr effect at large laser intensity: impact on the propagation of a short and intense laser pulse
2010
Talk given by O. Faucher; International audience
Higher-order Kerr terms allow ionization-free filamentation in gases
2010
Talk given by J. Kasparian; International audience; Higher-order nonlinear indices, rather than plasma, provide the main defocusing contribution to filamentation in gases at 800 nm. Developing generalized Miller formulae, we discuss the generality of this as a function of the laser wavelength
Measurement of the soliton number in guiding media through continuum generation.
2020
No general approach is available yet to measure directly the ratio between chromatic dispersion and the nonlinear coefficient, and hence the soliton number for a given optical pulse, in an arbitrary guiding medium. Here we solve this problem using continuum generation. We experimentally demonstrate our method in polarization-maintaining and single-mode fibers with positive and negative chromatic dispersion. Our technique also offers new opportunities to determine the chromatic dispersion of guiding media over a broad spectral range while pumping at a fixed wavelength. (C) 2020 Optical Society of America
Signal processing in photonic crystals and nanostructures
2006
International audience; Optical devices employing photonic crystals and novel nanostructure materials may exhibit useful properties for applications to all-optical signal processing. In this work we analyze as a first example four-wave mixing of polarized beams in photonic crystal fibers. We show that by properly tuning the pump wavelength and the linear dispersion properties of the fiber one may obtain broadband parametric amplification and frequency conversion. Next we consider the in-line periodic amplification of short optical pulses by means of quantum-dot semiconductor optical amplifiers. We show by numerical simulations that pattern-free amplification of a 40 Gbit/s soliton signal at…
Pulsating B and Be stars in the Small Magellanic Cloud
2008
Context: Stellar pulsations in main-sequence B-type stars are driven by the kappa-mechanism due to the Fe-group opacity bump. The current models do not predict the presence of instability strips in the B spectral domain at very low metallicities. As the metallicity of the SMC is lower than Z=0.005, it constitutes a very suitable object to test these predictions. Aims: The main objective is to investigate the existence of B-type pulsators at low metallicities, searching for short-term periodic variability in absorption-line B and Be stars in the SMC. The analysis has been performed in a sample of 313 B and Be stars with fundamental astrophysical parameters accurately determined from high-res…
Regeneración de cartílago mediante el uso de células madre de pulpa dental humanas (hDPSCs)
2020
El tejido cartilaginoso es un tejido fundamental, puesto que proporciona sostén a nuestro organismo. Cuando el cartílago articular se lesiona experimenta una regeneración compleja y limitada. Por ello es importante buscar alternativas y ampliar las soluciones que se están utilizando actualmente para tratar enfermedades en las que se produce la alteración del cartílago articular, como la osteoartritis. Con la base en esta idea, recientemente la ingeniería tisular ha desarrollado distintas herramientas para tratar de regenerar el cartílago cuando la regeneración por otras vías no es posible. Dentro de las estrategias que existen, se ha potenciado el uso de hidrogeles combinados con condrocito…
"Iam nouus in terras alto descendit Olympo Iuppiter” : Patronage and propaganda in the time of Leo X (1513–1521)
2022
Giovanni de’ Medici (1475–1521), son of Lorenzo il Magnifico, was destined to a brilliant ecclesiastical career that eventually led him to the Holy See as pope Leo X (1513–1521). His reign, marked by wars and the emergence of protestantism, was also a period of intense artistic activity in Rome, with Raphael, Michelangelo, Sangallo as well as a plethora of humanist authors engaged in celebrating Leo’s feats. This article explores Leo’s patronage and propaganda, in particular through an analysis of one of the numerous poems dedicated to him by Giano Vitale Castalio of Naples (Ianus Vitalis Castalius, c. 1485–c. 1560) at the beginning of his pontificate. peerReviewed
