Seminar Prof. Bouman, TODAY, Wednesday May 23rd, 2012, 11am (Birck 2001)
by Turner, Jaime J 23 May '12

23 May '12

Please attend if possible. ******************************** Birck/ECE Seminar Model Based Imaging Charlie Bouman Michael J. and Katherine R. Birck Professor of ECE Purdue University May 23rd, 2012 @ 11:00am Birck 2001 Abstract: Over the last two decades, model-based imaging techniques have emerged as a principled framework for understanding and solving many of the most important problems in imaging research. The approach of model-based imaging is to construct a model of both the image and the imaging system, and then to use this integrated model to either reconstruct an unknown image, or to estimate unknown parameters. The power of model-based methods is that they provide an optimal framework for solving a wide-range of imaging problems. So for example, model-based image reconstruction and parameter estimation can be used to robustly form images from sensors with uncertain calibration. But in addition, model-based imaging can serve as a framework for optimizing the static and dynamic design of imaging sensor systems themselves. In this talk, we review some techniques and recent successes in model-based imaging. Two application domains that we consider are tomographic reconstruction from multislice helical-scan CT and electron microscopy, two very different sensors that share much in common when viewed from the perspective of model-based imaging. For both cases, we discuss a variety of technical innovations, which either improve image quality or reduce the computational burden. We then show results, which demonstrate the value of the methods both quantitatively and qualitatively, on a variety of real and simulated datasets. Finally, we conclude with a philosophical discussion of the future potential of model-based methods, and we present some emerging ideas in prior modeling of images, which have potential to substantially improve upon current results. Bio: Charles A. Bouman is the Michael J. and Katherine R. Birck Professor of Electrical and Computer Engineering at Purdue University where he also holds a courtesy appointment in the School of Biomedical Engineering and serves has a co-director of Purdue's Magnetic Resonance Imaging Facility. He received his B.S.E.E. degree from the University of Pennsylvania, M.S. degree from the University of California at Berkeley, and Ph.D. from Princeton University in 1989. Professor Bouman's research focuses on inverse problems, stochastic modeling, and their application in a wide variety of imaging problems including tomographic reconstruction and image processing and rendering. Prof. Bouman is a Fellow of the IEEE, AIMBE, IS&T, and SPIE. He has served as the Editor-in-Chief of the IEEE Transactions on Image Processing, Distinguished Lecturer for the IEEE Signal Processing Society, a member of the IEEE Signal Processing Society's Board of Governors, and the Vice President of Publications for the IS&T Society. Currently, he is Vice President Elect for Technical Directions of the IEEE Signal Processing Society. ********************************

Dear All, I encourage you to attend the seminar below. Thanks for your time. Best regards, Ali Ali Shakouri Mary Jo and Robert L. Kirk Director Professor of Electrical and Computer Engineering Birck Nanotechnology Center, Room 1027 Purdue University 1205 West State Street West Lafayette, IN 47907-2057 (765) 496-6105; Fax: (765) 496-8299 shakouri(a)purdue.edu *************************************** Materials and physics for future high-speed RF and power devices and circuits: challenges and opportunities Professor Debdeep Jena, University of Notre Dame Thursday May 10th, 1:30-2:30pm Morgan 121 Abstract: As the age of scaling of Silicon transistors hits quantum mechanical brick walls, there is another age of electronics that is dawning. The new age is of ubiquitous high-performance RF and power electronics, where the key metric is energy efficiency. This new age of electronic devices and circuits pose significant challenges in developing new materials, investigating new physics, and innovations in circuits and systems. Therein also lies the opportunity for material scientists, electrical engineers, and physicists. In this presentation, I will highlight our research efforts in materials and devices that address this challenge. In particular, we have investigated wide bandgap semiconductor epitaxy and polarization physics originating from broken symmetry that enables functionalities absent in traditional semiconductors. The new physics and material properties drive the RF and power performance of such semiconductors to levels unmatched by traditional semiconductors. Emerging materials such as 2D crystals enhance these functionalities, and allow facile integration. The performance levels of such devices require radical rethinking of device physics, thermal management, and circuit and system architectures. Thus they offer significant opportunities for novel design. What is rather surprising is that the fundamental quantum limits of RF and power devices are poorly understood today, offering significant opportunities for physicists. In the talk, I wish to convey my personal excitement and vision about the future of this truly interdisciplinary endeavor. Bio: Debdeep Jena received the B. Tech. degree with a major in Electrical Engineering and a minor in Physics from the Indian Institute of Technology (IIT) Kanpur in 1998, and the Ph.D. degree in Electrical and Computer Engineering at the University of California, Santa Barbara (UCSB) in 2003. He joined the faculty of the department of Electrical Engineering at the University of Notre Dame in 2003. His research and teaching interests are in the MBE growth and device applications of quantum semiconductor heterostructures (currently III-V nitride semiconductors for RF and power applications), charge transport in nanostructured semiconducting materials such as graphene, nanowires and nanocrystals, and their device applications, and in the theory of charge, heat, and spin transport in nanomaterials. He is the author on several journal publications, including articles in Science, Physical Review Letters, and Electron Device Letters among others. He has received two best student paper awards in 2000 and 2002 for his Ph.D. dissertation research, the NSF CAREER award in 2007, and the Joyce award for excellence in undergraduate teaching in 2010. ***************************************

Cleanroom Citizenship issues
by Shakouri, Ali 10 May '12

10 May '12

To ALL Cleanroom Users The overall cleanliness and orderliness of the cleanroom has deteriorated over the last several weeks to the point of adversely affecting research and productivity of other users. As a reminder, all users are responsible for cleaning up after themselves and for leaving their work areas ready for use by others. Effective immediately, if any user is observed leaving a mess in a hood or near equipment, or leaving an unattended tote not in its proper storage location, they will be subjected to mandatory participation in weekly cleanings for one month, or a one-week suspension of all cleanroom privileges. This means denied access to the cleanroom for one week. Ali Shakouri Mary Jo and Robert L.

Best regards, Ali ******************************************************** SEMINAR WEDNESDAY, May 2, 2012 1:15 P.M. ROOM BRK 2001 Current Status of Large-Scale InP Photonic Integrated Circuits Fred A. Kish Sr. Vice President, Optical Integrated Components Group Infinera Corporation Abstract The current state-of-the-art for large-scale InP photonic integrated circuits (PICs) is reviewed with a focus on the devices and technologies that are driving the commercial scaling of these highly integrated devices. Specifically, high-capacity dense wavelength division multiplexed (DWDM) transmitter and receiver photonic integrated circuits (PICs) are reviewed with a focus next generation devices: >500 Gb/s and 1 Tb/s coherent multi-channel transmitter and receiver InP PICs. These large-scale PICs integrate hundreds of devices onto a single monolithic InP chip and enable significant reductions in cost, packaging complexity, size, fiber coupling, and power consumption which enable benefits at the component and system level. Biography Fred A. Kish received his Ph.D. (1992) in electrical engineering from the University of Illinois at Urbana-Champaign. From 1992 to 1999, he was at Hewlett-Packard's Optoelectronics Division where he co-invented and led the commercialization of the highest performance (efficiency) red-orange-yellow visible LEDs produced to date with efficiencies exceeding halogen lamps. From 1999 to 2001, he was with Agilent Technologies Fiber Optics Components Division as the III-V Department Manager. There, he led the department that developed commercially viable 2.5 Gb/s vertical cavity surface-emitting lasers (VCSELs) and VCSEL/detector arrays (12 x 2.5 Gb/s) for next generation fiber-optic transceiver and the first parallel-optic transmitter/receiver products. In 2001, he joined Infinera as Vice President of Photonic Integrated Circuit (PIC) Department, and is now Sr. Vice President of the Optical Integrated Components Group. At Infinera, he co-invented and led the effort to develop the first practical (commercial) large-scale PICs.

Our current research topics on GaN electronics include high-speed transistors, power switches, and THz devices based on an NDR-gated plasmonic channel to realize THz emission, detection and amplification. Graphene, an atomically thin 2D crystal with zero bandgap, has been touted for many intriguing applications, particularly for transparent touch screens and wearable electronics. Its optoelectronic properties are equally noteworthy. We successfully constructed THz modulators using graphene for the first time, another new avenue for graphene research. Tunnel FETs are promising replacements of Si-MOSFETs beyond 2020 due to their promise to achieve Ion/Ioff > 103 with Ion > 100 uA/um at low supply voltages (up to 0.5 V). To date we have demonstrated Ion/Ioff ~ 106, Ion ~ 50 uA/um. Challenges ahead include electrostatic control, defect-assisted tunneling and interface state density and parasitics. Biography Huili (Grace) Xing is currently the John Cardinal O'Hara CSC Associate Professor of Electrical Engineering at the University of Notre Dame. She obtained B.S. in physics from Peking University (1996), M.S. in Material Science from Lehigh University (1998) and Ph.D. in Electrical Engineering from University of California, Santa Barbara (2003), respectively. Her research focuses on development of III-V nitride and 2-D crystal semiconductor growth and (opto)electronic devices, especially the interplay between the material quality and device developments. More recent research interests include THz and bioelectronic applications. She is a recipient of AFOSR Young Investigator Award and NSF CAREER Award. ********************************************************
