Research Description

Weisbuch's research activities deal mainly with optics of semiconductors, and physics and applications of low-dimensional structures such as quantum-well and quantum-dot lasers. His recent research is on fundamental properties of coupled semiconductors and optical fields in microcavities and photonic crystals, as well as applications to new families of high performance light emitters.


Claude Weisbuch is a distinguished professor in the department of Materials, shool of engieering, UCSB. Weisbuch has been a researcher at the Laboratoire de Physique de la Matière Condensée at the Ecole Polytechnique as a director of research for the Centre National de la Recherche Scientifique (CNRS) since 1997. He is co-author of Quantum Semiconductor Structures: Physics and Applications (1991), a widely used, graduate-level text, and co-editor of five other books: Physics and Fabrication of Microstructures and Microdevices (1986); Physics, Fabrication and Applications of Multilayered Structures (1988); Confined Electrons and Photons: New Physics and Applications (1995); Microcavities and Photonic Bandgaps (1997), and Confined Photon Systems (1999). Weisbuch a fellow of the American Physical Society in 1993, he received the 1999 Welker Prize for his fundamental contributions to the understanding of the physics of quantum semiconductor structures and the development of novel optoelectronic device concepts.
