LECTure ENG PHYS ineering
Venue: Burke Science Building (BSB) 119 Tuesdays from 5.306.30 PM FALL 2015 ENGineering PHYSICS Department of Engineering Physics in the Faculty of Engineering at McMaster University, Canada. adriaan buijs is one of only a few countries that have developed its own type of civilian nuclear power reactor, the CANDU, which currently supplies about 50% of Ontario’s electricity. This presentation highlights the fundamentals of nuclear power, and highlights the special features of the CANDU reacotr. In the context of the International Year of the Light, Adriaan will highlight the important role high-energy photons play in the control of the CANDU reactor. vincent hamel of-the-art, multi-spectral airborne surveillance systems, L-3 Wescam is pursuing the most demanding applications in the defense market. This presentation will review some of the challenges faced when designing and manufacturing modern imaging systems. jon bradley Assistant Professor in the Dept. of Engineering Physics Rare Earth Lasers on a Silicon Microchip: Like silicon micro-and nanoelectronics in the second half of the 20th century, we are experiencing a revolution in photonics where microsystems can be built on a compact silicon chip. One of the challenges has been the integration of a laser, since silicon has an indirect bandgap and is generally an inefficient light emitter. Rare-earthdoped glasses offer a cost-effective, monolithic and flexible solution for silicon-based lasers. In this talk, I will discuss recent advancements from materials development and integration methods, to waveguide, microcavity and pulsed lasers, to their emerging applications in silicon photonic systems. ben rouben Ultra Short Light Pulses: Physics and Applications: Our ability to control light has increased since the advent of the laser. Photonic science has on one hand enabled high precision measurements using narrow lindwidth lasers, and on the other hand has opened many scientific avenues with the development of ultrashort pulsed lasers. The speaker will give an overview of the physics behind the generation and measurement of femtosecond duration light pulses. Adjunct Professor in the Dept. of Engineering Physics TUES 3 NOVEMBER An Overview of Modern Electro-Optic Imaging Systems for Airborne Surveillance: With its line of state- leandro tessler The Origins and the Why of the CANDU Reactor: The CANDU nuclear-reactor design is a unique Canadian homegrown nuclear technology. Its roots go back to Canada’s research in nuclear fission in WWII. In 1987, the CANDU program was named “One of Canada’s Top Ten Engineering Achievements of the Past Century”. This presentation will review the origins of the CANDU, the rationale of it, and the effect and import of the decisions made. Gleb Wataghin Institute of Physics (IFGW), University of Campinas TUES 1 DECEMBER talk will focus on the luminescence of rare earth (CE, Tb, Eu) doped silicon oxides, nitrides, and carbides, and some of the challenges in developing electrically driven lighting cells suitable for SSL and in particular, the development of white light emitters from rare earth doped Si-based materials. Professor in the Dept. of Engineering Physics Engineering Manager L3 Wescam Electro-Optical Design TUES 24 NOVEMBER Visible Light Emission from Silicon-Based Thin Film Nano-Structures: This harold haugen TUES 06 OCTOBER Delayed Photo-Neutrons in CANDU Reactors: Canada TUES 27 OCTOBER Risk and Fear: People often accept and enjoy dangerous activities such as skydiving and cycling without a helmet, and are afraid of things with little risk, such as rare diseases, radiation, and nuclear power plant accidents. This dichotomy has become more pronounced with time, and is reflected not just in attitudes to radiation but also to corporal punishment, terrorism, helicopter parenting, etc. This talk explores examples of inconsistent risk and fear, including the perceived vs. actual public health effectsof very severe nuclear power plant accidents. Overcoming fear is not easy, and even the industry can be unwittingly complicit. series Professor and Undergraduate Associate Chair Professor of Engineering Physics TUES 10 NOVEMBER peter mascher While the concepts of nanotechnology date back to the Richard Feynman, the terminology was not in regular use until the mid 80’s. By that time, the first commercially successful nanotechnology was already well on its way to transforming society with significant contributions from Canada (and McMaster). I will present the case that the first commercially successful nanotechnology was the semiconductor telecommunication laser. This remarkable device played a pivotal role in enabling our modern information age. Owner VGS Solutions, Program Director in UNENE TUES 20 OCTOBER victor snell The First Nano-Technology: TUES 29 SEPTEMBER Associate Dean, Research and External Relations TUES 22 SEPTEMBER john preston LECTure Rare Earth Elements in Amorphous Silicon Alloys: Rare Earth elements are not included in the main Periodic Table and have to be accommodated in a special place below it. However, some of their properties make them very important for applications in photonics and may be key elements for electronics-photonics integration. I will explain the reasons for their ostracism. I will present properties of Rare Earth doped amorphous silicon alloys, in particular results of photoluminescence and structural characterization by X-ray absorption spectroscopy (XANES and EXAFS). Indeed, the optical properties of the Rare Earth elements are determined by their immediate neighborhood.
