Research Area

Research Interests

Photonics is emerging as a multidisciplinary new frontier of science and technology and is capturing the imagination of scientists and engineers worldwide because of its potential applications to many areas of present and future information and image processing technologies. Photonics is the analog of electronics in that it describes the technology in which photons instead ofelectrons are used to acquire, store, transmit, and process information. Nonlinear optics provides key operational functions needed for the implementation of photonics technology. See also the UB Institute for Lasers, Photonics and Biophotonics website.

Our Photonics Research Laboratory is engaged in multidisciplinary research in the field of photonics and nonlinear optics. It has excellent research facilities for a comprehensive multidisciplinary research program and features state-of-the-art instrumentation.
