Abstract:

Analog photonic technologies have been employed to critical applications, including RF frontends, channelized EW receivers, true time delay beam forming, low noise oscillators, and various sensor systems. Wide adaptation of the photonic solutions strongly depends on chip level integration of an entire analog photonic system in order to achieve superior size, weight, efficiency and power (SWaP) performance. In this talk we will present our contributions to novel photonic devices and photonic integrated circuits for high dynamic range RF frontend. We will also discuss our current efforts in developing integrated RF/photonic links on a photonic chip, which is the foundation for building the integrated photonic solutions for aforementioned applications.  

Biography:

Prof. Yifei Li received his B.Eng. in Optoelectronics from Huazhong University of Science and Technology, China, in 1996. He received his MS (2001) and PhD (2003) in Electrical Engineering both from Drexel University, Philadelphia, PA. From 2003 to 2007, he was a research assistant professor with the Center for Microwave / Lightwave Engineering, Drexel University. During this period, he was also a senior microwave engineer in a Technology Startup making microwave power amplifiers, switches and phase shifters using GaN wide bandgap transistors. In 2007, he joined the ECE Department of the University of Massachusetts, Dartmouth, MA, where he is an associate professor and the director of the RF/Photonics Lab. Dr. Li is a visiting faculty with the Optoelectronic Group in the University of California Santa Barbara.  Dr. Li has four US patents in the area of RF/Photonics. He has numerous publications in renowned technical journals and international conference proceedings. Dr. Li is a winner of European Microwave Association (EuMA) Young Scientist Prize (1st prize) during the 12th Colloquium on Microwave Communications held in Budapest, Hungary. He is a winner of 2008 DARPA MTO Young Faculty Award. As a PI or co-PI, Dr. Li has lead 10 competitive US federal grants with combined funding of ~ $4.5M.
