Séminaire : Maxime Chambonneau : Taming nonlinear propagation of ultrashort laser pulses in silicon for devising innovative applications

November 24, 2022
14:00

Le 24 novembre prochain aura lieu une conférence sur les impulsions laser dans le silicon, donnée par Maxime Chambonneau un chercheur de l'Abbe center of Photonics de l'université Friedrich-Schiller à Iéna en Allemagne. Cette conférence aura lieu en salle A301 sur le site d'Illkirch. L'horaire reste encore à déterminer.

Titre : Taming nonlinear propagation of ultrashort laser pulses in silicon for devising innovative applications

 

Résumé

In-volume ultrafast laser direct writing is a proven technique for tailoring the properties of dielectrics (e.g., glasses, polymers) in a three-dimensional, fast, and contactless way. Nevertheless, to date, this technique has no equivalent for silicon, which is the backbone of today’s semiconductor industry. The strong limitations preventing the material from the production of internal laser-induced permanent modifications originate from nonlinearities governing the propagation of ultrashort laser pulses in silicon. Solutions have been developed for remedy this issue, thus holding promises for countless applications such as contactless 3D integration of photonic and electronic circuits in monolithic silicon, ultrafast laser welding as well as wafer dicing.
