The aim of this project is the conception, fabrication and study of Sb-based interband cascade and quantum cascade lasers grown onto different substrates (GaSb, InAs, GaAs and Si) for the realization of low cost optical sensors.


In the framework of the Hyquality French BPI project between IES and the two companies mirSense and EASIIC, we are looking for a postdoctoral/researcher. The research will be held at IES, in the Nanomir team in partnership with the two industrial partners. The candidate will be involved in the development of interband and quantum cascade lasers (ICL and QCL) emitting between 4 and 9 µm. He/She will be able to perform the modelling of the laser band structure and determine the associated electro-optical properties (gain, threshold voltage and current,…). The main part of the work will be carried out in the cleanroom to develop the process of these lasers which will be realized on different substrates (GaSb, InAs, GaAs and Si). He/She will also participate in the studies of the devices to determine the electro-optical performances.


By the starting date, the applicant should have a PhD degree in Engineering Physics, with a solid background in semiconductor physics and process. A strong experience in the following area is required: Process technology in cleanroom, modelling of semiconductor laser and electro-optical characterizations
Fluency in English is mandatory.

Work Context

The Institut d'Électronique et des Systèmes is a joint research center between the CNRS and the University of Montpellier (IES, UMR n°5214 CNRS-UM). This center regroups nine research teams covering several research areas from materials, photonics and waves to sensors and instrumentation. The Nanomir group is specialized in semiconductor Sb-based optoelectronic devices (laser, detector and sensor) working in the mid-infrared wavelength range.

Constraints and risks

Work in cleanroom environment, use of mid-infrared lasers
