Our research group studies and develops novel laser processing technology for defining photonic devices, optical circuits, microfluidic and other nanostructures. The laser enables fabrication in novel two- and three-dimensional architectures to be explored in optical materials for broad impact in today's optical communication networks and lab-on-a-chip microsystems.
