QPL at UCSB

About The Lab

In the Quantum Photonics Lab, we develop nanophotonic and optoelectronic technologies for a wide range of applications – from optical quantum computing to communications, networking, and sensing. Our efforts are focused on addressing important challenges in these areas through the design, fabrication, and testing of heterogeneous integrated quantum photonic devices, the exploration of new quantum materials and systems, and the development of ultra-sensitive measurement techniques for benchmarking device performance spanning visible to telecommunication wavelengths, cryogenic to ambient temperatures, and DC to RF frequencies. Specific areas of interest are quantum photonic integrated circuits based on AlGaAs, silicon nitride, lithium niobate, and silicon, hybrid electro-optomechanical quantum systems, and nanophotonics with engineered quantum emitters.
