Axel Scherer

Axel Scherer is the Bernard Neches Professor of Electrical Engineering, Physics, and Applied Physics at the California Institute of Technology. He is also a Distinguished Visiting Professor at Thayer School of Engineering at Dartmouth College. He is known for fabricating the world's first semiconducting vertical-cavity surface-emitting laser (VCSEL) at Bell Labs. In 2006, Dr. Scherer was named the director of the Kavli Nanoscience Institute. He graduated from New Mexico Institute of Mining and Technology in 1985. At Caltech he teaches a very popular freshman lab course on semiconductor device fabrication: Applied Physics 9ab, for which he wrote the textbook for the course.
His research focuses on the design and microfabrication of optical, magnetic and fluidic devices. In the 1980s, Axel Scherer pioneered the development of the first monolithic vertical cavity lasers (VCSELs) that are now widely used in data communications systems. More recently, Professor Scherer's group developed electromagnetic design tools and fabrication techniques for the definition of lithographically integrated optical devices. This led to pioneering work in photonic bandgap lasers, silicon photonic circuits, as well as tunable microfluidic dye lasers, and resulted in new classes of integrated optics. The first demonstration of strong coupling between single quantum dots and optical nanocavities recently emerged from a collaboration between Axel Scherer and Hyatt Gibbs. Collaborations with Larry Dalton (University of Washington) resulted in some of the world's smallest and fastest light modulators. Professor Scherer also fabricated some of the first surface Plasmon enhanced high brightness light emitting diodes. His group miniaturized fluidic systems and demonstrated the first multi-layer replication molded fluidic chips, with thousands of valves creating microfluidic “laboratories” and single cell analysis systems. Scherer has co-founded several companies in the area of silicon photonics and biomedical diagnostics, and leads a productive group focused on the miniaturization and integration of fluidic, optical, electronic and magnetic devices for applications in biotechnology.
Professor Scherer has co-authored over 300 publications and holds over 50 patents on the area of microfabrication and design of devices.
He is also co-founder and an advisor to Luxtera, a California manufacturer of photonics devices.
He is also co-founder and an advisor to Helixis, a California manufacturer of molecular diagnostic devices. Helixis was acquired by Illumina in 2010.
He is also co-founder and an advisor to ChromaCode, a California manufacturer of molecular diagnostic reagents.
Scherer is a fellow of the National Academy of Inventors.
