The language of Einstein spoken by optical instruments [PDF]
, 2004 Einstein had to learn the mathematics of Lorentz transformations in order to complete his covariant formulation of Maxwell's equations. The mathematics of Lorentz transformations, called the Lorentz group, continues playing its important role in optical ...

Quantum optics with bosons and fermions [PDF]
, 2008 Atom optics, a field which takes much inspiration from traditional optics, has advanced to the point that some of the fundamental experiments of quantum optics, involving photon correlations, have found atomic analogs.

Inverse design enables large-scale high-performance meta-optics reshaping virtual reality [PDF]
Nature Communications, 2021 Meta-optics has achieved major breakthroughs in the past decade; however, conventional forward design faces challenges as functionality complexity and device size scale up.

Optical Vortices shape Optical Tornados
Optics Express, 2023 We demonstrate that by seeding an accelerating ring-Airy beam with a finite number of off-axis optical vortices, it transforms into a Tornado wave (ToW) upon propagation. Using numerical simulations, we show that both the spiraling high-intensity lobes and the optical vortices exhibit angular acceleration and follow interwinding braid-like trajectories.

Polarization singularities from unfolding an optical vortex through a birefringent crystal [PDF]
, 2004 Optical vortices (nodal lines and phase singularities) are the generic singularities of scalar optics but are unstable in vector optics. We investigate experimentally and theoretically the unfolding of a uniformly polarized optical vortex beam on ...

Defectoscopic Tests of Smoke Mortar Charges [PDF]
Problemy Mechatroniki, 2015 There are presented selected results of defectoscopic tests on smoke charges confined in the metallic containers inserted in the bodies of 98 mm mortar bombs, using Real Time Rentegenoscopy (RTR) and infrared (IR) thermography.
