Description of the thesis topic

The PhD candidate goal is to develop a new theme around mid-infrared quantum optoelectronic devices. The objective of the project is the realization of frequency combs in inter-band cascade lasers in the infrared region between 3 μm to 5 μm. This objective will be achieved through an integrated geometry where all these properties are realised on a chip (system-on-chip SOC) resulting in a miniature frequency comb for dual frequency comb applications such as ultra-sensitive detection of environmental and industrial gases.

Work Context

The thesis will be built around the activities below:
- Development of ultra-fast experiments to characterize and understand the dynamics of the new quantum devices.
- Compare theoretical and experimental results.
- Carry out new experiences and develop new devices from models
- Prepare scientific articles and participate in congresses and conferences

This work will be funded by the ANR “ACTIVE-COMB” project coordinated by Sukhdeep Dhillon. The work will be carried out in the LPENS nanoTHz team and will be part of the team's research activities around the ultrafast properties of optoelectronic devices.
