Dr. Vladimir A. Aksyuk Seminar JANUARY 29, 2018 11:30 AM - 12:30 AM BRK 1001 Title: Integrated Photonic and Plasmonic Signal Transduction for Micro- and Nanomechanical Sensing Bio: Vladimir Aksyuk is a Project Leader at the NIST Center for Nanoscale Science and Technology. He received a B.S. from Moscow Institute of Physics and Technology and a Ph.D. in Physics from Rutgers University, and worked as a Technical Manager at Bell Laboratories prior to joining NIST. Vladimir's research focuses on microsystems tightly coupling optical, plasmonic, electrical, thermal and mechanical degrees of freedom at the nanoscale. He received a Distinguished Alumni award for early career accomplishments from Rutgers and the Bell Labs President's Gold Award, was named among MIT Technology Review magazine's TR35, and awarded a Bronze Medal by NIST. He is a Fellow of the American Physical Society recognized for contributions to the development of integrated photonic and mechanical microsystems, for pioneering work in using such systems to enable both telecommunications and novel nanoscale, high-throughput measurement methods, and for contributions to the understanding of the Casimir force. Abstract: Measuring unknown quantities by coupling them to mechanical motion dates back at least 5000 years: simple equal-arm balances used for weighing goods in ancient Egypt are in fact mechanical measurement tools, with motion detected optically by the human eye. Modern microfabrication enables sophisticated, high performance 100 micrometer scale physical sensors, while in the quest for ever faster and more precise measurement of vastly smaller forces, masses, as well as other quantities, mechanical tools have now been reduced to well below one micrometer in at least two of the three physical dimensions. Even at sub-wavelength dimensions, light remains a competitive and, in many cases, superior choice for the mechanical signal detection, for both fundamental and engineering reasons. Optomechanical interactions are strongly enhanced by high quality factor nanophotonic resonators, localizing photons and extending interaction times, making possible quantum-limited nanoscale motion readout at modest optical power and with low power dissipation. Si photonics technology transforms these devices into fiber-connectorized, compact, robust, stable and practical sensors requiring no optical alignment. Their superior precision and bandwidth have recently been used to advance Atomic Force Microscopy, replacing traditional microscale cantilevers and their laser-readout optics. Similar, integrated cavity-optomechanical detection has been employed to characterize nanoscale stress-controlled SiN tuning fork resonators which exhibit some of the highest measured fQ products and show great practical promise for precise, high bandwidth, and high bias stability on-chip motion measurement. Integration of gap-plasmonic resonators into nanomechanical systems achieves not only precise but truly local motion measurement, confined to a 100 nm scale footprint, capable of spatially distinguishing between NEMS mechanical modes. Broadband and lossy nature of plasmonics allows the use of white light for motion readout and enables very compact thermo-optically driven plasmomechanical oscillators. These examples illustrate the significant, yet largely unexplored, technological potential of highly integrated transducers combining Si photonics, MEMS, NEMS, cavity-optomechanics and plasmonics.

FW: PAL Service Alert
by Turner, Jaime J 23 Jan '18

23 Jan '18

From: Kercher-Updike, Julie D [mailto:jkercher@purdue.edu] Sent: Tuesday, January 23, 2018 3:25 PM To: Turner, Jaime J <jjbiggs(a)purdue.edu> Subject: PAL Service Alert I am writing to update you on a recent issue with access to PAL, the campus wireless system, which ITaP is working diligently to resolve. We are aware that some people are having difficulty connecting to the PAL network on the West Lafayette campus. On any given day, there are more than 36,000 devices connected to PAL. As of this morning, we are seeing 96 percent of the devices connecting and are cautiously optimistic that we are resolving the issue. I want to assure you that ITaP staff and high-level CISCO engineers are on-site working to troubleshoot this issue. In some cases, the troubleshooting requires complete disruptions in service, but we are trying to limit these disruptions. Our investigation thus far is pointing to a problem with the way authentication is taking place. Individuals connected to PAL in a single location appear to stay connected. However, those who roam from one place to another require re-authentication. In some instances, re-authentication happens seamlessly. In others it may take more than three or four tries to get connected. We have found that these workarounds help in many cases: * Use the Eduroam network instead of PAL: Purdue users can connect to Eduroam by entering their Purdue email address as their user name (username(a)purdue.edu<mailto:username@purdue.edu>) and their Purdue password. Instructions for connecting to Eduroam with multiple devices and operating systems can be found at https://www.purdue.edu/goldanswers/308500. * Remove then re-add PAL: In the wireless settings on your device, forget or delete PAL as the preferred wireless network. Then re-select PAL from the list of available networks. This may take a few tries before the PAL connection is restored. If it doesn't work on the second try, wait 10 minutes and try again. * If you continue to have connection issues, please call the ITaP Customer Service Center at 44000, email itap(a)purdue.edu<mailto:ITaP@purdue.edu>, or visit the walk-in help desks in the HSSE Library or WALC. We continue to closely monitor the situation and will continue aggressive troubleshooting in trying to reach 100% connectivity. Thank you for your patience, Julie Julie Kercher-Updike AVP of IT Process Management, & Deputy CIO Purdue University 765.496.2272<tel:765.496.2272> www.itap.purdue.edu<http://www.itap.purdue.edu>

Hui Cao Seminar - Jan. 22nd, 11:30am in MRGN 129
by Turner, Jaime J 17 Jan '18

17 Jan '18

Professor Hui Cao Seminar JANUARY 22, 2018 11:30 AM - 12:30 PM MRGN 129 Mesoscopic Optics BIO: Hui Cao received her Ph.D. degree in Applied Physics from Stanford University in 1997. Her doctoral research was in the area of semiconductor microcavity quantum electrodynamics. Prior to joining the Yale faculty in 2008, Professor Cao was on the faculty of the Department of Physics and Astronomy at Northwestern University from 1997 to 2007. Her technical interests and activities are in the areas of complex photonic materials and devices, nanophotonics, and biophotonics. She has co-authors one book and ten book-chapters, and has published more than 230 research papers in the areas of mesoscopic optics, random lasers, optical microcavities, photonic crystals, and structural coloration. ABSTRACT: Random scattering of light, e.g., in paint, cloud and biological tissue, is a common process of both fundamental interest and practical relevance. The interference of multiply scattered waves leads to remarkable phenomena in mesoscopic physics such as the formation of open and closed transmission channels. In applications, optical scattering is the main obstacle to imaging or sending information through turbid media. Recent developments of adaptive wavefront shaping in optics enabled imaging and focusing of light through opaque samples. By selective coupling to open or closed channels, we varied the transmission of a laser beam through a highly scattering system by two orders of magnitude, and drastically changed the energy density distribution inside the system. Furthermore, by adding optical gain to a disordered medium, we realized random lasing and demonstrated its application to speckle-free full-field imaging. Finally, we developed a fast and efficient method of switching the spatial coherence of a laser, and applied it to multimodal microscopy.

by Leidy Lab 11 Jan '18

11 Jan '18

Hello, We are recruiting for our ongoing protein shake study (see below). Are there benefits to eating different types of protein? You can help answer this question by taking part in our study! You will be provided different types of breakfast shakes to consume at home. For each type of breakfast shake, you will complete a 5-h testing day that measures your feelings of appetite (hunger & fullness) and thoughts of food, and hormones that respond to eating (by taking blood samples in our lab). If you qualify, you will be paid for completing all study procedures. For more information contact: leidylab(a)purdue.edu<mailto:leidylab@purdue.edu> and mention: The Protein Source Study. IRB# 1701018659 Thank you! Sincerely, The Leidy Lab
