About
Mathieu Bertrand is a Researcher in the Department of Physics at ETH Zürich, part of the Institute of Quantum Electronics under Prof. Faist's group. His research focuses on mid-infrared quantum cascade lasers (QCLs), particularly on frequency combs, dual-comb interferometry, and RF properties enhancement. He has contributed to advancing technologies such as surface-emitting QCLs and low-dissipation devices.
Education: He holds a graduate degree from Grenoble-INP Phelma (France/Grenoble), specializing in semiconductor physics and optoelectronics.
Research interests include quantum walk combs, RF-modulated QCLs, and applications in spectroscopy. His work bridges theoretical and experimental physics, with contributions to both fundamental science and practical device development.
Teaching: He has taught at ETH Zürich since 2020, including courses on Quantum Optics, Physics Practica, and IT infrastructure management. Previously, he taught electromagnetism at Polytech' Grenoble (2017–2019).
Projects: Current projects include developing low-dissipation Quantum Cascade Surface Emitting Lasers (QCSELs) and advancing fiber networks for optical signal distribution. Side projects involve lab automation, interferometer design, and data processing tools.
Collaborations: Works with D-ITET on fast signal detection and maintains a lab laser database. Enjoys interdisciplinary projects blending physics, engineering, and design.
