Limits on the free-space group velocity of optical wave packets incorporating angular dispersion. Part~II, non-differentiable angular dispersion: tutorial
Layton A. Hall, Ayman F. Abouraddy
In Part~I of this tutorial, we showed that introducing angular dispersion (AD) into a collimated optical pulse allows for tuning the wave packet group velocity in free space. In pr…
Limits on the free-space group velocity of optical wave packets incorporating angular dispersion. Part~I, conventional angular dispersion: tutorial
Layton A. Hall, Ayman F. Abouraddy
A plane-wave optical pulse travels in free space at a group velocity (the speed of light in vacuum) measured along its propagation axis. It is sometimes thought that spatially…
Diagonalizing an optical coherence matrix via on-chip Stokes tomography
Amin Hashemi, Abbas Shiri, Bahaa E. A. Saleh +2
Structured coherence -- partially coherent light spanned by a finite number of modes -- is emerging as a powerful tool in optical communications, computation, cryptography, and spe…
Structured coherence: A modern perspective on optical coherence as a resource
Ayman F. Abouraddy, Bahaa E. A. Saleh
Optical coherence is a well-established branch of physical optics in which the statistical properties of fluctuating optical fields are described in terms of correlation functions…
Selective avoidance of multiple line-of-sight obstacles at 130~m using locally bending space-time wave packets
Layton A. Hall, Murat Yessenov, Isabelle Lebron +1
Self-accelerating optical beams follow curved trajectories rather than propagating rectilinearly, which raises the prospect for avoiding line-of-sight (LoS) obstacles blocking the…
Avoiding a line-of-sight obstacle via deep sub-Rayleigh shadow-projection utilizing space-time wave packets
Layton A. Hall, Bryan L. Turo, Ayman F. Abouraddy
A challenge in optics, which is shared by other sources of radiation, is to direct a coherent beam to impinge on a target behind an obstacle intervening in the line-of-sight (LoS).…
