Our research group pioneers advanced laser processing technologies for fabricating photonic devices, optical circuits, microfluidic systems, and other nanoscale structures. By harnessing ultrafast nonlinear interaction physics and diffractive beam shaping, we enable the creation of novel three-dimensional architectures embedded within transparent optical materials. These innovations open new pathways for manufacturing and device integration in applications such as optical communication networks, co-packaged photonics, security and anti-counterfeit films, and lab-on-a-chip microsystems.
We foster a collaborative and dynamic training environment rooted in excellence in discovery, innovation, and leadership. This excellence is driven by our people—their curiosity, motivation, and commitment to learning. We are dedicated to building an equitable and inclusive community that values diversity and is grounded in mutual respect and dignity, in alignment with the University's Statement on Equity, Diversity, and Inclusion (EDI).
