The Optoelectronics Circuits and Systems Laboratory at UCLA performs multi-disciplinary research and development in the fields of communication and sensing. The Lab has two complementary missions. The first is to solve critical problems faced by Defense and Commercial industries through innovative approaches thatenable revolutionary advances in devices or systems. The second and equally important mission is to produce creative and highly skilled engineers who will be the driving force for technological innovation in the 21st century. The Lab enjoys the strong support of the US Defense Department and private companies.
