  1. Computer Graphics Imagery for Motion Pictures and Commercial Advertising: The Achievement of Highly-Realistic Images

    19 Aug 2011 | | Contributor(s):: Kenneth Torrance

    The talk will review some of the underlying concepts from Radiation Heat Transfer that have now been implemented in synthetic images. In many cases, researchers in graphics have created algorithms that are many times faster and more detailed than the engineering algorithms from which they were...

  4. Quantitative Modeling and Simulation of Quantum Dots

    18 Apr 2011 | | Contributor(s):: Muhammad Usman

    Quantum dots grown by self-assembly process are typically constructed by 50,000 to 5,000,000 structural atoms which confine a small, countable number of extra electrons or holes in a space that is comparable in size to the electron wavelength. Under such conditions quantum dots can be...

  9. A Half Century of Nonlinear Optics

    22 Mar 2011 | | Contributor(s):: Robert W. Boyd

    In this talk, we first present a review of the development of the field of nonlinear optics, and we then survey some areas of recent research including quantum imaging and implications of the ability to control the group velocity of light.

  10. Anti-Reflection Coating Assignment

    30 Nov 2010 | | Contributor(s):: Alex Small

    This is a guided activity for students to study the design of an anti-reflection coating. The student is first asked to do a simple calculation by hand, to determine the proper thickness for an anti-reflection coating in a standard situation. The student then uses the nanoHUB tool "PhotonicsRT:...

  11. Peanuts vs. Pyramids: Two Perspectives on MEMS

    29 Dec 2009 | | Contributor(s):: Stephen D. Senturia

    MEMS, the acronym for Micro-electromechanical Systems, also known simply as “Micro-systems,” come in two main types: commodity products (the peanuts) and MEMS-enabled products (the pyramids, or, more correctly, the inverted pyramids). The economics of scale greatly affect how these two classes...

  14. Experiment vs. Modelling: What's the problem?

    05 Jun 2009 | | Contributor(s):: William L. Barnes

    Progress in plasmonics has been greatly assisted by developments in experimental techniques and in numerical modelling. This talk will look at some of the difficulties that emerge when comparisons are made between experiment and theory. Through the use of four examples I will illustrate what...

  15. The Optical Freqency Comb: A Remarkable Tool for Metrology, Science and Medical Diagnostics

    31 Dec 2008 | | Contributor(s):: John L. Hall

    The Optical Frequency Comb concept and technology exploded in 1999-2000 from the synthesis of advances in independent fields of Laser Stabilization, UltraFast Lasers, and NonLinear Optical Fibers. The Comb was developed first as a method for optical frequency measurement, enabling a...
