Professor. Baile Chen received his bachelor degree in physics from Department of Modern Physics in University of Science and Technology of China in Hefei, China, in 2007. He received his master degree in physics and Ph.D degree in electrical engineering both from University of Virginia, Charlottesville, VA, USA in 2009 and 2013, respectively. After he finished his PhD, he worked in the large multi-national RF company, Qorvo Inc (formerly Triquint Semiconductor), Hillsboro, Oregon, USA. As a result, he understood how a company is operating, right from business planning, product design to maufacturing. This helps Professor Chen work with industrial partners and do useful research. In Qorvo, he mainly focused on various RF power amplifiers and BAW filters in multi-band LTE wireless handset. In January, 2016, he joined in the School of Information Science and Technology in Shanghai Tech University as a tenure track assistant professor.

The recent explosive growth in communications has been brought about by fiber optic and wireless communications technologies. These two technologies have merged to create an interdisciplinary area called microwave photonics, including RF optical links, oscillators, and radar. The research in the Optoelectronics Devices Group at ShanghaiTech University is focused on the development of optoelectronic components and technologies that enable new applications and advances in microwave photonic systems. One of the key devices for the signal generation in microwave photonic systems is the high-speed, high power photodiode. Our work includes the development of state-of-the-art Silicon based, GaAs based, InP based high-speed, high power photodetectors and arrays.
The vast majority of research on silicon photonics has focused on devices operating within near-infrared (NIR) telecommunication bands from 1310nm to 1550nm wavelength. This has been driven by the low cost photonics fabricated with existing complementary metal-oxide-semiconductor (CMOS) infrastructure and the large market for telecommunications with the ever increasing demands. Our group collaborated with University of London College works on the monolithic integration of III-V SWIR/MWIR photonic devices on Silicon. These technologies can offer potentially high performance, high yield and low cost products, which will reshape the current mid-infrared market significantly.
Short-wavelength infrared (SWIR)/mid-wavelength infrared (MWIR) have a wide range of applications in free space communications, gas monitor, chemical sensing and medical applications. Our group works on InP based on InGaAs/GaAsSb(Bi) type-II multiple quantum wells for laser diodes and photodiodes applications, which enjoys the mature process technologies developed by InP based fiber optics communications.
