Title: From `DC to Daylight’: Reunifying the Electro-magnetic Spectrum in       Silicon and the Opportunities it Opens up Speaker: Prof. Kaushik Sengupta, Princeton University Date: 6/16(Tue) 14:30-15:30Place: 東京工業大学大岡山キャンパスAbstract:After Maxwell reunified the Electro-magnetic spectrum in the 1850s,the spectrum broke on frequency lines into separate, specialized andmature disciplines of study. Almost a century and half later, we see areunification of electromagnetism in one single platform, opening upopportunities to create cutting-edge technology for thenext-generation systems. Having the ability to synthesize, control andmanipulate such a large portion of the spectrum (DC-THz) with abillion transistors in a single platform, silicon, opens up a plethoraof opportunities spanning a wide range of applications in sensing,imaging, spectroscopy, medical diagnostics, communication and beyond.Such unprecedented levels of integration can be leveraged only weremove the artificial partitions among various levels of abstractionin system design such as analog, digital, electromagnetics, antenna,communication and control theory and take a holistic approach.  In this talk, I will show some practical examples how such an approachenables us to go beyond transistor speed limits into the terahertzfrequency range (0.3-3 THz), demonstrating the first CMOS THzbeam-scanning array, an all-silicon active terahertz imaging systemand generation and radiation of pico-second pulses capable of dynamicspectral shaping. The intersection of analog, digital and RF createsnew opportunities for novel and robust system design and, we willdiscuss a fully integrated, closed loop and autonomous self-healingmm-wave power amplifier capable mitigating process variations, loadmismatches and unintentional failures. If time permits, we willdiscuss how manipulating optical fields in silicon can lead tomultiplexed sensor arrays in CMOS for bio-molecular diagnostics.

Bio: Kaushik Sengupta received the B.Tech. and M.Tech. degrees inElectronics and Electrical Communication engineering from the IndianInstitute of Technology (IIT), Kharagpur, India, both in 2007, and theM.S. and Ph.D. degrees in electrical engineering from the CaliforniaInstitute of Technology, Pasadena, CA, USA, in 2008 and 2012,respectively.  In February 2013, he joined the faculty of the Department ofElectrical Engineering, Princeton University, Princeton, NJ, USA. Hisresearch interests are in the areas of high-frequency integratedcircuits (ICs), electromagnetics, optics for various applications insensing, imaging and high-speed communication. Dr. Sengupta was therecipient of the IBM Ph.D. fellowship (2011–2012), the IEEESolid-State Circuits Society Predoctoral Achievement Award, the IEEEMicrowave Theory and Techniques Society (IEEE MTT-S) GraduateFellowship, and the Analog Devices Outstanding Student Designer Award(2011). He was also the recipient of the Charles Wilts Prize in 2013from the Department of Electrical Engineering, California Institute ofTechnology for the best PhD award in Electrical Engineering. He wasselected in Princeton Engineering Commendation List for OutstandingTeaching in 2014. He was also the recipient of the Prime Minister GoldMedal Award of the Indian Institute of Technology (IIT) (2007), theCalifornia Institute of Technology Institute Fellowship, , and theIEEE MTT-S Undergraduate Fellowship (2006). He was the corecipient ofthe IEEE RFIC Symposium Best Student Paper Award in 2012 and the IEEEMicrowave Prize in 2015 for the best paper in IEEE Transactions onMicrowave Theory and Techniques published in 2013.
