Profile overview
Who is Federico Capasso?
Federico Capasso is an inventor associated with Italy. Their documented work in industrial & manufacturing includes Quantum-cascade laser, the contribution at the center of this evidence-backed profile.
The semiconductor laser uses engineered quantum wells to emit mid-infrared light, providing compact sources for sensing, spectroscopy and industrial measurement that conventional lasers could not efficiently supply. The device architecture turned semiconductor physics into a compact, deployable measurement source.
What did Federico Capasso invent?
Co-invented the quantum-cascade laser with Jérôme Faist and colleagues.
What did Federico Capasso accomplish?
Quantum-cascade lasers created a major commercial class of semiconductor light source.
What is known about Federico Capasso today?
Harvard's March 2026 faculty profile identifies Capasso as a current professor.
