Anomalous refraction of optical space-time wave packets
Basanta Bhaduri, Murat Yessenov, Ayman F. Abouraddy
Refraction at the interface between two materials is fundamental to the interaction of light with photonic devices and to the propagation of light through the atmosphere at large.…
Free-space optical delay line using space-time wave packets
Murat Yessenov, Basanta Bhaduri, Peter J. Delfyett +1
An optical buffer having a large delay-bandwidth-product -- a critical component for future all-optical communications networks -- remains elusive. Central to its realization is a…
Non-diffracting broadband incoherent space-time fields
Murat Yessenov, Basanta Bhaduri, H. Esat Kondakci +3
Space-time (ST) wave packets are coherent pulsed beams that propagate diffraction-free and dispersion-free by virtue of tight correlations introduced between their spatial and temp…
Broadband space-time wave packets propagating 70 m
Basanta Bhaduri, Murat Yessenov, Danielle Reyes +6
The propagation distance of a pulsed beam in free space is ultimately limited by diffraction and space-time coupling. "Space-time" (ST) wave packets are pulsed beams endowed with t…
What is the maximum differential group delay achievable by a space-time wave packet in free space?
Murat Yessenov, Lam Mach, Basanta Bhaduri +5
The group velocity of 'space-time' wave packets propagation-invariant pulsed beams endowed with tight spatio-temporal spectral correlations can take on arbitrary values in…
Classification of propagation-invariant space-time wave packets in free space: Theory and experiments
Murat Yessenov, Basanta Bhaduri, H. Esat Kondakci +1
Introducing correlations between the spatial and temporal degrees of freedom of a pulsed optical beam (or wave packet) can profoundly alter its propagation in free space. Indeed, a…
