Novel Silicon Nanophotonic Structures for Ultra-compact Integrated Lab-on-a-chip Sensing
No full textProfesssor Ali Adibi from the School of Electrical and Computer Engineering presented a lecture at the Nano@Tech Meeting on March 11, 2008 at 12 noon in room 102 of the MiRC buildingRuntime: 60:36 minutesThe development of ultra-compact and sensitive sensing structures with minimal sample requirement for accurate sensing have been of great recent interest for multiple applications including bio and environmental sensing, chemical agent detection, and bio- threat detection. With recent advancement in the development of design and fabrication tools for photonic nanostructures, integrated photonic platforms are a strong candidate for the development of such sensing structures.
In this talk, Prof. Ali Adibi first presented the requirements for the development of photonic lab-on-a-chip sensing structures. Then he explained how these requirements are met by two recent developments in our group in the area of silicon photonics, i.e., ultra-high Q micro-resonators, and ultra-compact photonic crystal on-chip spectrometers with orders of magnitude smaller size compared to the other implementations with the same performance. These spectrometers are enabled by dispersion engineering in photonic crystal to simultaneously achieve the superprism effect, negative diffraction, and negative refraction. Details of the design of such structures along with their experimental demonstrations will be presented
The Complete Muhammad Ali
No full textIncluding material and photographs not included in most of the 100 other books about the champion, Ishmael Reed's The Complete Muhammad Ali is more than just a biography-it is a fascinating portrait of the 20th century and the beginning of the 21st. An honest, balanced portrayal of Ali, the book includes voices that have been omitted from other books. It charts Ali's evolution from Black Nationalism to a universalism, but does not discount the Nation of Islam and Black Nationalism's important influence on his intellectual development. Filipino American author Emil Guillermo speaks about how "The Thrilla' In Manila" brought the Philippines into the 20th century. Fans of Muhammad Ali, boxing fans, and those interested in modern African American history and the Nation of Islam will be fascinated by this biography by an accomplished American author.Intro -- DEDICATION -- INTRODUCTION -- The Curious History of an Icon -- CHAPTER 1 -- CHAPTER 2 -- CHAPTER 3 -- CHAPTER 4 -- CHAPTER 5 -- CHAPTER 6 -- CHAPTER 7 -- Did the Secret Government Fear a U.S. Muslim/Overseas Muslim Alliance? -- CHAPTER 8 -- CHAPTER 9 -- The Break Between the Prophet and his Disciple -- CHAPTER 10 -- CHAPTER 11 -- CHAPTER 12 -- The GOAT (Greatest Of All Time): Ali or Louis? -- CHAPTER 13 -- The Nation of Islam, the Mob, Showdowns in Canada and Sonny Liston -- CHAPTER 14 -- CHAPTER 15 -- The Taunts: Marketing or Racism? -- CHAPTER 16 -- CHAPTER 17 -- CHAPTER 18 -- CHAPTER 19 -- Boxing and the Brain -- CHAPTER 20 -- Ali's Feet -- CHAPTER 21 -- Mr. Dick -- CHAPTER 22 -- CHAPTER 23 -- The Opening Ceremonies, November 2005 -- CHAPTER 24 -- December 2005, Las Vegas -- CHAPTER 25 -- CHAPTER 26 -- June 16, 2004 -- CHAPTER 27 -- CHAPTER 28 -- CHAPTER 29 -- Aix-en-Provence -- CHAPTER 30 -- Ali as a Black Nationalist -- San Francisco, January 2004 Black Liberation Book Fair -- CHAPTER 31 -- January 31, 2004 -- CHAPTER 32 -- October 2005, Chicago -- CHAPTER 33 -- Why Ali remained with Elijah instead of following Malcolm -- CHAPTER 34 -- CHAPTER 35 -- February 4, 2006, Oakland, California -- CHAPTER 36 -- Like Zeus Descending from Mount Olympus -- CHAPTER 37 -- CHAPTER 38 -- Tuesday, February 28, 2006, New York -- CHAPTER 39 -- Bigger Than Boxing -- CHAPTER 40 -- Tribes Gallery, New York, April 2006 -- CHAPTER 41 -- June 2006, Louisville, Kentucky -- CHAPTER 42 -- CHAPTER 43 -- CHAPTER 45 -- Bad Company -- CHAPTER 46 -- Coxson, A Very Charming Rogue -- CHAPTER 47 -- Ali and the largest embezzlement scheme in Wells Fargo history -- CHAPTER 48 -- CHAPTER 49 -- "Lonnie is a stabilizing force."-Harry Belafonte -- October 29, 2006 -- CHAPTER 50 -- Abdul Rahman -- CHAPTER 51 -- CHAPTER 52 -- CHAPTER 53How Will Ali Be Remembered?

Controlling group velocity in rectangular-lattice photonic crystal waveguides
No full textA method for controlling the dispersion and thus group velocity of guided modes in photonic crystal (PC) waveguides using bi- and quasi-periodic lattices is presented. Rectangular lattice photonic crystals are proposed as possible candidates for implementing such control. However, these structures, and generally all bi-periodic lattices, develop undesirable characteristics as the perfect square lattice is perturbed. Thus, quasi-periodic photonic crystals, which have been shown to be promising in selective mode engineering, were examined next. A possible scheme for engineering of a single mode PC waveguide with guiding through the entire bandgap is presented

Syriac-Arabic Glosses of Isho bar Ali. Volume 2
No full textThese two volumes constitute the second part (nun-taw) of the Syriac-Arabic dictionary of the 10th cent. physician Isho bar Ali (the first half of the dictionary had been published in 1874 by G. Hoffmann). Each Syriac word is defined in Arabic, often with more than one Arabic equivalent; in addition, the author deals not just with individual Syriac words, but in some cases with phrases. Gottheil used 21 manuscripts (from Oxford, London, Paris, Berlin, Leiden, and Rome) for this edition, and he has supplied a thorough critical apparatus; the manuscripts are described in the introduction. While some manuscripts give the Arabic glosses in Syriac characters (i.e. Garshuni), Gottheil has presented them here in Arabic script. These two volumes will be of great interest to Syriac lexicographers and those who study interactions between Syriac and Arabic.Contains an English introduction by Richard J.H. Gotthei

Proceedings of SPIE: Wavelength-resolved Purcell enhancement of PbS/CdS quantum dots measured on a chip-based platform
No full textFuture quantum optical networks will require an integrated solution to multiplex suitable sources and detectors on a low-loss platform. Here we combined superconducting single-photon detectors with colloidal PbS/CdS quantum dots (QDs) and low-loss silicon nitride passive photonic components to show their combined operation at cryogenic temperatures. Using a planar concave grating spectrometer, we performed wavelength-resolved measurements of the photoluminescence decay of QDs, which were deterministically placed in the gap of plasmonic antennas, in order to improve their emission rate. We observed a Purcell enhancement matching the antenna simulations, with a concurrent increase of the count rate on the superconducting detectors.ImPhys/Optic
Hybrid Material and Device Platforms for Reconfigurable Integrated Nanophotonics
No full textPresented on November 27, 2018 at 12:00 p.m.-1:00 p.m. in the Marcus Nanotechnology Building, Room 1117-1118, Georgia Tech.Ali Adibi is the director of Bio and Environmental Sensing Technologies (BEST) and a professor and Joseph M. Pettit chair in the School of Electrical and Computer Engineering, Georgia Institute of Technology. His research group has pioneered several structures in the field of integrated nanophotonics for both information processing and sensing. He is the author of more than 150 journal papers and 400 conference papers. He is the editor-in-chief of the Journal of Nanophotonics, and the nanophotonic program track chair of the Photonics West meeting. He is the recipient of several awards including Presidential Early Career Award for Scientists and Engineers, Packard Fellowship, NSF CAREER Award, and the SPIE Technology Achievement Award. He is also a fellow of OSA, SPIE, and AAAS.Runtime: 51:02 minutesThe development of ultra-compact integrated nanophotonic structures for communications, sensing, and signal processing has been of great interest lately. Recent progress in the development of miniaturized high-Q microresonators has resulted in orders of magnitude reduction in the size of functional integrated photonic structures. The possibility of low-power tuning of the resonance features in these structures has made the formation of reconfigurable photonic structures possible. Among existing CMOS-compatible substrates, silicon (Si) and silicon nitride (SiN) have been used the most. Despite impressive progress in Si-based and SiN-based integrated photonics, neither substrate alone can be used for practical applications. Si (despite its good reconfigurability) suffers from strong nonlinear effects (especially at high light intensities) and relatively large free-carrier loss while SiN (with one order of magnitude lower loss and lower nonlinearity compared to Si) is very hard to tune. Thus, a reliable material system that combines ultra-loss-loss and high power handling with efficient and fast reconfigurability is of high demand in integrated nanophotonics. In this talk, the recent achievements in the development and optimization of hybrid multi-layer CMOS-compatible material systems (e.g., SiN/Si, multi-layer Si/SiO2, etc.) to address all the practical requirements of ultra-fast and ultra-compact integrated photonic structures will be discussed. Using these hybrid material systems, a series of ultra-compact and high-performance reconfigurable photonic devices and subsystems that are formed by using high Q resonators will be demonstrated. The use of these devices and subsystems for realization of densely-integrated reconfigurable photonic chips for signal processing and sensing applications will be discussed
The Transcultural Critic: Sabahattin Ali and Beyond
No full textThe central theme of this volume is the work of Sabahattin Ali, the Turkish author and translator from German into Turkish who achieved posthumous success with his novel Kürk Mantolu Madonna (The Madonna in the Fur Coat). Our contributors analyze this novel, which takes place largely in Germany, and several other texts by Ali in the context of world literature, (cultural) translation, and intertextuality. Their articles go far beyond the intercultural love affair that has typically dominated the discussion of Madonna. Other articles consider Zafer Şenocak’s essay collection Deutschsein and transcultural learning through picture books. An interview with Selim Özdoğan rounds out the issue.Im Mittelpunkt dieses Bandes steht das Werk des türkischen Autors und Übersetzers aus dem Deutschen Sabahattin Ali, der mit seinem Roman Kürk Mantolu Madonna (Die Madonna im Pelzmantel) zu posthumem Ruhm gelangte. Der Roman, der zum Großteil in Deutschland spielt, und andere seiner Werke werden unter Aspekten der Weltliteratur, (kultureller) Übersetzung und Intertextualität diskutiert. Damit reicht der Fokus weit über die bislang im Vordergrund stehende interkulturelle Liebesgeschichte in der Madonna hinaus. Weitere Beiträge beschäftigen sich mit Zafer Şenocaks Essaysammlung Deutschsein und dem transkulturellen Lernen mit Bilderbüchern. Ein Interview mit Selim Özdoğan rundet diese Ausgabe ab
