Sample Projects
All-Optical Buffering of
Images in Slow-Light Medium 2006-2007
Optical pulses in an imaging system are buffered in a Cesium vapor cell.
Pulses are delayed up to 10 nanoseconds.
Fiber scans of 10 nanometer resolution via LabView
to reconstruct image.
Press coverage in Washington Post and Scientific America Online.
Quantum Key Distribution
(QKD) in Fiber Using Entangled Photon Pairs 2004-2007
BMP image is transmitted over digital network using generated key.
100 femtosecond long photon pairs are
generated in parametric down-conversion.
Photon arrival times recorded and synchronized to 50 picoseconds
resolution.
Co-inventor and joint patent holder of cryptographic technique.
Quantum Imaging with
Entangled Photons 2004-2007
Investigate imaging enhancement and other free-space applications.
Research lithography, bio-imaging and other novel techniques.
Collaborative
project obtained $147M in 2005 from Department of Defense.
Masters
Candidate, Theoretical Quantum Optics Group 2001
Advisor: Prof. P. Knight
Investigate entanglement in rudimentary solid-state system by modeling
in C++.
