Today's Colloquium

October 8.  3:30 p.m.  Meinel 307

 

Robert Norwood, University of Arizona College of Optical Sciences, will present Optical Polymer Nanocomposites:  Designer Materials for Nanophotonics.  Mahmoud Fallahi is the host.

 

Abstract:  Major breakthroughs in photonics have often occurred when superb materials science is coupled with elegant and efficient device design/fabrication.  Silica-based optical fiber, the semiconductor laser, the erbium doped fiber amplifier and the silica-on-silicon arrayed waveguide grating router are several notable examples of this phenomena.  State-of-the-art photonics now requires the development of ever-higher degrees of integration, placing stringent demands on photonic materials technology, which ultimately must be suitable for the new field of nanophotonics.  In parallel with these developments, the field of optical polymer nanocomposites (PNC) has emerged thanks to considerable advances in optical polymer materials, nanoparticle synthesis, nanoparticle functionalization and dispersion techniques.  Optical PNCs have the potential to fulfill a broad range of photonic functions ranging from compact, narrowband filters, to electro-optical modulation at hundreds of GHz.  To accomplish this, a clear understanding of optical polymer and nanoparticle properties is required, as well as an ability to effectively model and predict the properties of the PNC, and finally align these properties with the photonics engineering problem at hand.  We will discuss our recent work on optical PNCs, including PNC infiltrated silicon photonic crystals, polymer/InP nanowire composites, and magneto-optic PNCs.

No Colloquium Next Week

 

Our October 15 Colloquium is cancelled so everyone can attend OSA's Frontiers in Optics 2009/Laser Science XXV.   Colloquium will resume on October 22 when Yong-Hang Zhang of Arizona State University Department of Electrical Engineering and Director of the Center for Nanophotonics will present 6.1 Å II-VI and III-V Semiconductors and Their Application to Multi-Junction Solar Cells.

OSC Team Shows Quantum Fingerprints of Chaos

 

This morning's issue of the prestigious scientific journal Nature features a paper by Poul Jessen, three OSC graduate students: Souma Chaudhury, Aaron Smith, and Brian E. Anderson, and Shohini Ghose of Wilfrid Laurier University.  The paper, Quantum Signatures of Chaos in a Kicked Top, is published in the Letters section. 

 

From the Nature index:  "There has been a long-standing search for quantum signatures of classical chaos. Here, an atomic system that can be used to study quantum chaos — the quantum kicked top — is experimentally realized and directly observed to reveal dynamics in quantum phase space that have a chaotic classical counterpart. Clear differences are noted in the sensitivity to perturbation in chaotic versus regular regimes and dynamical entanglement is proposed as a signature of chaos."

 

The full text is available on-line:  S. Chaudhury, A. Smith, B.E. Anderson, S. Ghose, and P.S. Jessen, Quantum Signatures of Chaos in a Kicked Top, Nature 461, 768-771 (8 October 2009)  www.nature.com/nature/journal/v461/n7265/full/nature08396.html

 

The paper is gathering quite a lot of attention.  For more information, please see the following:

Our Industrial Affiliates Program:  A Little Background Info

 

The mission of OSC's Industrial Affiliates Program is to provide a venue for today's optics corporations and organizations to partner with us in our mission to educate the next generation of optical scientists and optical engineers.

 

For companies, some of the immediate benefits of Affiliate membership include strong ties to our College, an invitation to our bi-annual Workshop, and very exclusive employee recruitment assistance.

 

The membership dues paid by Affiliate companies are used to enhance the entire college and particularly the needs of our students.  Membership fees from our Industrial Affiliates make a significant difference in the quality of the educational opportunities and financial assistance that we are able to offer our students.

 

Our Fall Workshop for Industrial Affiliates is scheduled for later this month:  on Tuesday, October 27 and Wednesday, October 28 and we hope to see everyone there.  Meanwhile, thank you Affiliates, for your interest in our students and for your support.
