UCF Researchers Set Record Fastest Light Pulse
2017/9/4
A research team at the University of Central Florida has demonstrated the fastest light pulse ever developed, a 53-attosecond X-ray flash.The group led by Professor Zenghu Chang beat its own record se...
The excitation of a two-level atom by a propagating light pulse
The excitation two-level atom propagating light pulse
2010/11/8
State mapping between atoms and photons, and photon-photon interactions play an important role in scalable quantum information processing. We consider the interaction of a two-level atom with a quant...
Focusing of a femtosecond vortex light pulse through a high numerical aperture objective
Ultrafast phenomena Singular Optics Diffraction Theory
2013/7/2
We investigate the focusing properties of a femtosecond vortex light pulse focused by a high numerical aperture objective. By using the Richards-Wolf vectorial diffraction method...
Stopping and time reversing a light pulse using dynamic loss tuning of coupled-resonator delay lines
time reversing light pulse dynamic loss tuning coupled-resonator delay lines
2015/8/10
We introduce a light-stopping process that uses dynamic loss tuning in coupled-resonator delay lines. We demonstrate via numerical simulations that increasing the loss of selected resonators traps lig...
