Research Description

Our research consists of three main areas: biomedical imaging, optical instrumentation, and optical communications. Our emphasis is on the practical applications of photonics and fiber optics, ranging from new concepts and devices to full-scale systems. Techniques involved include both numerical modeling and experimental investigations. Several industrial partners participate in this program, providing capabilities in the fabrication of specialty fibers and optoelectronic devices.
