ECE Professor Awarded Million Dollar Grant by Air Force

Dr. Yifei Li of the department of Electrical and Computer Engineering (ECE) was awarded a five year, one million-dollar grant by the Air Force Office of Research (AFOSR) to conduct fundamental research in Radio Frequency (RF)/Photonic integrated circuits. Dr. Li received his Ph.D. from Drexel University in 2003. In 2007, he joined the ECE department as an assistant professor. He has previously been funded in the field of RF/Photonics by the Office of Naval Research (ONR) and the Defense Advanced Research Projects Agency (DARPA). He was awarded the prestigious DARPA Young Faculty Award in 2008. Dr. Li has four US patents in the area of RF/Photonics.

The goal of AFOSR research project is to confirm the hypothesis that with the help of a novel Attenuating and Counter-Propagating (ACP) methodology a PM RF/photonic link integrated on a photonic IC can achieve a superior dynamic range as well as sufficient power and cost efficiency. The project contains three main thrust areas: (i) examine the interaction between optical and microwave fields in the ACP devices and investigate metamaterials for overcoming the limitations imposed by the ACP approach; (ii) study a novel detuned shallow quantum well structure for simultaneously realizing linear and quadratic optical phase modulation; and (iii) investigate the nonlinear dynamics of an optical phase locked loop receiver.
