[Physstaff] Reminder: Seminar today at 10:30m - Thierry Guillet from Université de Montpellier

[Thorsten Ackemann]

Hi

Just a reminder on the seminar this morning

Speaker: Thierry Guillet, Université de Montpellier, Faculté des 
Sciences / Laboratoire Charles Coulomb (L2C)
Title:  Nitride and ZnO-based photonics: from non-linear optics to novel 
microlasers
Date: 19th May 2015
Time: 10:30am
Location: JA5.06
Abstract: Wide bandgap semiconductors (GaN and nitride alloys, ZnO) 
provide a spectrally-broad transparency -expanding from the 
near-infrared to the ultraviolet- as well as robust excitons that are 
efficiently interacting with light and stable up to room temperature. 
They offer a promising playground for non-linear optics and micro- or 
nano-lasers at 300K. Over the last decade, the progresses of the 
nitrides’ processing has allowed to fabricate nanophotonic resonators 
and devices such that the interaction between excitons and photons can 
be tailored on demand. We will review our recent achievements, ranging 
from ZnO polariton lasers based on 2D vertical cavities, to UV-C GaN/AlN 
microdisk lasers and second-harmonic generation in photonic crystal 
cavities. These works result from collaborations with CNRS (CRHEA, LPN), 
and Orsay and Clermont-Ferrand Universities (IEF, IP).

regards,
Thorsten
