Paul Prucnal

Paul R. Prucnal (born 1953) is an American electrical engineer. He is a professor of electrical engineering at Princeton University. He is best known for his seminal work in Neuromorphic Photonics, optical code division multiple access (OCDMA) and the invention of the terahertz optical asymmetric demultiplexor (TOAD). He is currently a fellow of IEEE for contributions to photonic switching and fiber-optic networks, Optical Society of America and National Academy of Inventors. After his doctorate, Prucnal joined the faculty at Columbia University in 1979. As a member of the Columbia Radiation Laboratory, he performed groundbreaking work in OCDMA and self-routed photonic switching. In 1988, he joined the faculty at Princeton University.

His developmental research on optical CDMA initiated a new research field in which more than 1000 papers have since been published, exploring applications ranging from information security to communication speed and bandwidth. In 1993, he invented the "Terahertz Optical Asymmetric Demultiplexer," the first optical switch capable of processing terabit per second (Tb/s) pulse trains. With support from DARPA in the 1990s, his group was the first to demonstrate an all-optical 100 gigabit/sec photonic packet switching node and optical multiprocessor interconnect.

Prucnal is author of the book, Neuromorphic Photonics, for his paper entitled "Self-routing photonic switching with optically-processed control" and has won multiple teaching awards at Princeton. as well as integrated optical circuits to improve wireless signal quality by cancelling radio interference.

He resides in Princeton with his wife Mindy and daughters Jenny and Katie.
