The Norman Hascoe Distinguished Lecture Series
Vertical Cavity Lasers - New Light for the Information Age
Department of Electrical and Computer Engineering
University of Illinois at Urbana-Champaign
The infrastructure of the Information Age has to date relied upon advances in microelectronics to produce integrated circuits that continually become smaller, better, and less expensive. The emergence of photonics, where light rather than electricity is manipulated, is posed to further advance the Information Age. Central to the photonic revolution is the development of miniature light sources such as the vertical-cavity surface-emitting laser (VCSEL). Today, VCSEL manufacturing has been established to serve new datacom and telecom markets. Moreover, recent progress in microcavity physics, new materials, and fabrication technologies has enabled a new generation of high performance VCSELs. This presentation will review commercial VCSELs and their applications as well as discuss recent research, including new device structures such as composite resonators and photonic crystals, as well as applications of 2-dimensional VCSEL arrays.
