Design by Ana Pejkic



Our mission is to inspire scientific innovations and reveal methods to solving critical problems in communications, medicine, astronomy and security. To accomplish our goals, we have designed photonic devices and systems capable of establishing new records in signal speed, fidelity, and dissipation. Our state-of-the-art devices exploit linear and nonlinear optical interactions in silica fiber and semiconductor materials and are currently implemented as signal processors, agile oscillators and frequency combs. A key to our success is a unique facility developed over a decade-long period, located on UC San Diego campus in La Jolla.
