Profile overview
Who is Jérôme Faist?
Jérôme Faist is an inventor associated with Switzerland. Their documented work in industrial & manufacturing includes Quantum-cascade laser, the contribution at the center of this evidence-backed profile.
The quantum-well laser made compact mid-infrared sources practical for gas sensing and spectroscopy, translating engineered semiconductor layers into a consequential physical instrument platform. The demonstration established a semiconductor-light source platform for instruments used beyond research labs.
What did Jérôme Faist invent?
Co-invented and first demonstrated the quantum-cascade laser with Federico Capasso and colleagues.
What did Jérôme Faist accomplish?
Quantum-cascade lasers became a widely used semiconductor source for infrared measurement.
What is known about Jérôme Faist today?
ETH Zurich's May 2026 notice identifies Faist as its current full professor.
