Applications of Slow and Stopped Light
Prof. John C. Howell, University of Rochester
"Slow" and "Stopped" light have had a surge of interest. Slow light is a coined phrase which has been used to describe a slow group velocity of a pulse in a medium. The ability to tune the group velocity has potential applications in telecommunications, all-optical routers and buffers, remote sensing and optical pattern recognition. I will discuss some of our recent experimental results: Fourier transform interferometry, image buffering and preservation and entanglement preservation. Stopped light has been equally intriguing. In a stopped light system, a light field is mapped onto an internal degree of freedom in the medium such as an atomic spin wave. This has potential a low light level memory device such as a quantum memory. I will discuss one of our recent experiments in which we were able to store and preserve an image.
Prof. Howell received his B.S. in Physics (1995) with a minor in Mathematics from Utah State University, and his M.S. and Ph.D. in Physics (2000) from Pennsylvania State University. He then took a postdoctoral research position at the Centre for Quantum Computation at the University of Oxford. Prof. Howell joined the University of Rochester in 2002, as Assistant Professor of Physics. Howell received a Presidential Early Career Award for Scientists and Engineers in 2004, a Research Innovation Award from the Research Corporation in 2004, a Presidential PECASE Award in 2005, and the Adolph Lomb Medal from the Optical Society of America in 2006 "For innovative contributions in quantum optics, particularly aspects of quantum cloning, violations of Bell's inequalities and maximal photonic entanglement."
This meeting begins at 6:30 PM Thursday, May 8, 2008 and will be located in the cafeteria at MIT Lincoln Laboratory, 244 Wood Street, Lexington, MA 02420. The meeting is free and open to the public. All are welcome. Prior to the meeting there will be a speaker’s dinner which includes pizza and beverages, and will also be held at Lincoln Labs. The dinner will begin at 5:30 PM and is open to all attendees.

Quantum Imaging
Prof. Yanhua Shih, Physics Department, University of Maryland
One of the most surprising consequences of quantum mechanics is the entanglement of two or more distant particles. Although questions regarding fundamental issues of quantum theory still exist, quantum entanglement has started to play important roles in practical engineering applications. Quantum imaging is one of these exciting areas. Quantum imaging has demonstrated two peculiar features: (1) reproducing “ghost” images in a “nonlocal” manner, and (2) enhancing the spatial resolution of imaging beyond the diffraction limit. This talk will discuss these peculiar quantum effects with particular emphasis on the physics of spatial resolution enhancement and the “ghost” imaging phenomenon.
Yanhua Shih received his B.S. degree in theoretical physics from Northwestern University of China in 1981, and his Ph.D. in physics from the University of Maryland, College Park, in 1987. He joined the Faculty of the University of Maryland, Baltimore County in 1989 and established the Quantum Optics Program at UMBC. The Quantum Optics Laboratory of UMBC has been recognized as one of the leading laboratories in the field of quantum optics. He is currently Professor of Physics at UMBC. His research interests include fundamental problems of quantum theory and general relativity.
