Our lab designs, fabricates, tests, and integrates photonic devices and systems in silicon nitride. These devices leverage the low optical loss of silicon nitride to realize novel functionality such as ultra-high-Q waveguide resonators, narrow linewidth on-chip laser sources, and photonic molecules. We demonstrate these devices operating at the system scale in applications ranging from atomic-referenced metrology, to low power, ultra-high-capacity optical communications for tomorrow’s energy efficient hyperscale data centers.

Diversity, Equity, and Inclusion

We adhere to the basic principle that members of our community should treat each other with respect and decency at all times, and that we should not alienate, diminish, or insult each other, personally or professionally, either in word or deed. Based on this principle, we believe that well-being, respect, inclusion, collaboration, and mentorship are moral imperatives that are vital to our teaching and research mission. As individuals and as a community we constantly work to avoid all forms of discrimination, including explicit, implicit, and/or unintended bias.
