Paul K. Yu
Assoc VC/Res Initiatives, Electrical and Computer Engineering
Professor, Electrical and Computer Engineering
Microwave photonics, with research on electronic and opto-electronic devices and advanced materials for use in photonic devices. For twenty years, Professor Yu has been working on devices that enhance the performance of telecommunications networks. His current focus on transmitting microwave signals through optical fiber has the potential to revolutionize communications by paving the way for broadband speeds many times faster than today's advanced 10 Gigabit per second (Gbps) systems. While working on devices that may not reach the commercial market for five years or longer, Yu can speak about the challenges that academic and industry researchers face as they push fiber transmission speeds to 40Gbps and higher, while improving efficiency as well. Yu is also an expert on the increasing uses of photonic approaches to what had been exclusively electronic applications, and can explain advances in state-of-the-art photonic devices such as laser diodes, high power lasers, external modulators, optical amplifiers, and photodetectors. At UCSD, Yu is also part of the Materials Science and Engineering program and Institute of Engineering in Medicine. He works on new materials to be used in the construction of advanced optoelectronic devices.
