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,…
Broadband entangled-photon omni-resonance in a planar optical cavity
Bryan L. Turo, Layton A. Hall, Bahaa E. A. Saleh +1
Resonant field enhancement in an optical cavity is a promising pathway towards realizing optical nonlinearities at the few-photon level. This quest is hampered by inevitable narrow…
Bending space-time wave packets
Layton A. Hall, Ayman F. Abouraddy
Optical beams with certain asymmetric profiles, such as the Airy beam, can depart from rectilinear propagation and instead travel along curved (typically parabolic) trajectories. H…
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…
Ultrafast space-time optical merons in momentum-energy space
Murat Yessenov, Ahmed H. Dorrah, Cheng Guo +7
Skyrmions, topologically non-trivial localized spin structures, are fertile ground for exploring emergent phenomena in condensed matter physics and next-generation magnetic-memory…
