FOTON-INSA UMR CNRS 6082            

NEWS : The PhD subjects which will be proposed soon are now available ... PhD subjects

Our laboratory is dedicated to the study of the growth and the optoelectronic applications of semiconductor nanostructures (Quantum wells and quantum dots) on InP, GaP or Si substrates. The FOTON-INSA owns two MBE systems (one GSMBE and one SSMBE), and a LPCVD epitaxial chamber, a clean room and several facilities for optical and electrical characterisations as well as for calculations. Our activities span from fundamental studies on nanostructures (Quantum dots) to realisation of new optoelectronic devices such as microcavity MQW saturable absorbers, VCSELs or quantum dot lasers.

The FOTON-INSA laboratory, in association with the microelectronic group of IETR is recognised by the CNRS as a proximity technology center : "Nano-Rennes" . For a detailed presentation of the laboratory, see the video in french in (.avi)  :  video FOTON-INSA - 201 Mo

Research activities deal with five main research areas :

• Growth and studies of quantum dots based devices for telecommnuication  laser applications 
• Optical micro-cavities and tunable nanostructures-based VCSELs  for optical telecommunications
• III-V  Photonics on Silicon (integration of optics on Silicon, photovoltaics applications)
• development of  nanostructures-based light emitters for mid-infrared applications between 2 and 5 µm (gas detection, medical applications)
• nanothermals properties of semiconductors (recovery of thermal energy waste in semiconductors)

Within the laboratory, the research activities are divided into three categories of inequal importance, which have an impact on our organisation. The first one, which is related to fundamental research, help us to keep an expertise in the basics of the physics of nanostructures, and reinforce the second one, which is more applied, and related to our contractual relationship. The third one is focused on the development of new research subjects, keeping up with technological innovations, in order to prepare future studies.
