PREFACE By way of introduction to these symposium papers let us say a brief word first on the term “electronic art”and secondly on the focus of the symposium, “the art factor.” Our task is twofold: (1) to specify more clearly what we mean by “electronic art” and (2) to begin developing the critical understanding necessary for filtering out the finest artistic manifestations of its use. ELECTRONIC ART. Recently a colleague suggested that the term “electronic art” was an oxymoron. By this I believe she meant a self contradictory term. Several years ago when we contemplated this symposium I also questioned the use of the term “electronic” as did our committees and many others. But no longer. Changing technologies in the practice of art are not new. They have been with us from prehistoric times. Thus the art of the brushed Chinese character is “shufa”; the art of the manuscript is “calligraphy”; and the art of typesetting is “typography.“ Since World War II the field of electronics has achieved radically new capabilities and has attracted hundreds of artists to experiment with its use. There are over 1800 entries in the 1993 edition of the International Directory of EIecfronic Art. Although reference to “electronic” music dates back to as early as the sine-wave tones of Leon Theremin in 1924, it was the perfection of the tape recorder in the 1940’s that thrust electronic music forward. For the arts in general, the term has been in substantial use for several decades with a pronounced presence since the founding of “Ars Electronica” in 1979 at Linz, Austria. What is the new post WWII technology in electronics? It is the integrated circuit (1948) making possible the use of sophisticated logic circuitry in everything from desktop computers to cruise missiles. Today’s electronic controllers exhibit an uncanny capability - a semblance of “intelligence,” capable of flying airplanes, simulating the human voice and controlling vast networks of information. These controllers are driven by electronic circuits capable of processing logical procedures lending them a seemingly intelligent behavior. These procedures may be software controllable (open for instruction) and self adjusting to the environment they are designed to control. Procedures may be designed to simulate practically

Supervisor, Ehud Sharlin Department of Computer Science Co-Supervisor, Saul Greenberg Department of Computer Science Examiner, Sonny Chan Department of Computer Science External Examiner, Joshua Taron Faculty of Environmental Design Date Abstract Transparent displays are ‘see-through’ screens: a person can simultaneously view both the graphics on the screen and real-world content visible through the screen. Interactive transparent displays can serve as an important medium supporting face-to-face collaboration, where people interact with both sides of the display and work together. Such displays enhance workspace awareness, which smooths collaboration: when a person is working on one side of a transparent display, the person on the other side can see the other’s hand gestures, gaze, and what s/he is currently manipulating on the shared screen. Even so, we argue that in order to provide effective support for collaboration, designing such transparent displays must go beyond current offerings. We propose using two-sided transparent displays, which can present different content on both sides.

A profound understanding of the underlying physics has inspired the emergence of a new frontier of materials and devices in the past few decades. is thesis explores the concepts and approaches for manipulating light at the wavelength-scale in a variety of topics, including anti-reective coatings, on- chip silicon photonics, optical microcavities and nanolasers, microwave particle accelerators, and optical nonlinearities. In Chapter , an optimal tapered prole that maximizes light transmission be- tween two media with different refractive indices is derived from analytical theory and numerical modeling. A broadband wide-angle anti-reective coating at the air/silicon interface is designed for the application of photovoltaics.

ALSOLAMY has been approved for the Department of Physics and Astronomy and the College of Arts and Sciences by Eric A. Stinaff Associate Professor of Physics and Astronomy Robert Frank Dean, College of Arts and Sciences 3 ABSTRACT ALSOLAMY, SAMAR, M., M.S., May 2013, Physics and Astronomy The Study of Coupling in InGaAs Quantum Rings Grown by Droplet Epitaxy Director ofThesis: Eric A. Stinaff The use of metal droplet epitaxy may provide a novel method of growing laterally coupled nanostructures. We will present optical studies of InAs/GaAs nanostructures which result in twin quantum dots (QD) formed on a single quantum ring (QR). Previous studies have investigated the coupling between vertically grown quantum dot pairs. In this thesis, we have used photoluminescence (PL) and photoluminescence excitation (PLE) to examine the possibility of energy transfer and coupling between quantum dot pairs in a single InGaAs quantum ring grown by droplet epitaxy. Power dependent photoluminescence spectra reveal a few peaks at low power, which are identified with emission from the ground state of the individual dots. As the power is increased we observe multi-exciton and excited state emission. We then perform PLE, tuning the excitation laser energy continuously from the high energy ring emission down to the individual dot states.

  • A Solution-Processed 1.53 Μm Quantum Dot Laser with Temperature
    A solution-processed 1.53 μm quantum dot laser with temperature-invariant emission wavelength S. Hoogland, V. Sukhovatkin, I. Howard, S. Cauchi, L. Levina, E. H. Sargent The Edward S. Rogers Sr. Department of Electrical and Computer Engineering University of Toronto Toronto, ON, Canada, M5S 3G4 [email protected]; [email protected] Abstract: Sources of coherent, monochromatic short-wavelength infrared (1-2 μm) light are essential in telecommunications, biomedical diagnosis, and optical sensing. Today’s semiconductor lasers are made by epitaxial growth on a lattice-matched single-crystal substrate. This strategy is incompatible with direct growth on silicon. Colloidal quantum dots synthesized in solution can, in contrast, be coated onto any surface. Here we show a 1.53 μm laser fabricated using a remarkably simple process: dipping a glass capillary into a colloidal suspension of semiconductor quantum dots. We developed the procedures to produce a smooth, low-scattering-loss film inside the capillary, resulting in a whispering gallery mode laser with a well-defined threshold. While there exist three prior reports of optical gain in infrared-emitting colloidal quantum dots [1, 2, 3], this work represents the first report of an infrared laser made using solution processing. We also report dλmax/dT, the temperature-sensitivity of lasing wavelength, of 0.03 nm/K, the lowest ever reported in a colloidal quantum dot system and 10 times lower than in traditional semiconductor quantum wells. ©2006 Optical Society of America OCIS codes: (140.5960) Semiconductor lasers; (160.3380) Laser materials; (999.999) Nanocrystal quantum dots.

This is a true copy of the thesis, including any required final revisions, as accepted by my examiners.

Signature: ii ABSTRACT Natasha Dinyar Mody ‘Demystifying the Future of the Screen’ Master of Design, Digital Futures, 2018 OCAD University Demystifying the Future of the Screen explores the creation of a 3D representation of volumetric display (a graphical display device that produces 3D objects in mid-air), a technology that doesn’t yet exist in the consumer realm, using current technologies. It investigates the conceptual possibilities and technical challenges of prototyping a future, speculative, technology with current available materials. Cultural precedents, technical antecedents, economic challenges, and industry adaptation, all contribute to this thesis proposal. It pedals back to the past to examine the probable widespread integration of this future technology. By employing a detailed horizon scan, analyzing science fiction theories, and extensive user testing, I fabricated a prototype that simulates an immersive volumetric display experience, using a holographic display fan.
