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
The paper demonstrates pulsed space‑time wave packets whose spatiotemporal spectrum is engineered to locally bend around one or multiple line‑of‑sight obstacles, allowing the beam…
Self-healing of the Montgomery pattern
Athena Xu, Oscar de Vries, Alfonso Palmieri +3
Self-healing -- the ability of a structured beam to reconstruct its transverse profile after partial obstruction -- has been demonstrated for diffraction-free beams, where the reco…
Observation of spatially structured Montgomery effect in free space
Murat Yessenov, Luca Sacchi, Alfonso Palmieri +3
We report the first direct observation of the spatially structured Montgomery effect, a lensless self-imaging phenomenon that generalizes the Talbot effect to aperiodic structures,…
Universality and non-differentiability: A new perspective on angular dispersion in optics
Layton A. Hall, Murat Yessenov, Kenneth L. Schepler +1
Angular dispersion (AD) is a ubiquitous phenomenon in optics after light traverses a diffractive or dispersive device, whereby each wavelength propagates at a different angle. AD i…
Long-distance axial spectral encoding using space-time wave packets
Layton A. Hall, Murat Yessenov, Miguel A. Romer +1
Space-time wave packets (STWPs) are pulsed optical beams whose spatiotemporal structure enables propagation invariance. However, STWPs allow for a unique propagation configuration…
Optical spatiotemporal Fourier synthesis: Tutorial
Murat Yessenov, Ayman F. Abouraddy
Fourier synthesis is one of the foundations of physical optics. Spatial Fourier optics is a basis for understanding optical imaging, microscopy, and holography. In conventional Fou…
