Magneto-optical polarisation texturing

Koray Koksal, Fatma Tambag, Jamal Berakdar +1

Left and right circularly polarized transverse electromagnetic waves propagate at slightly different speeds in a magnetic material leading to a polarization rotation by an amount p…

Intrinsic angular momentum, spin and helicity of higher-order Poincare modes

Mohamed Babiker, Koray Koksal, Vassilis Lembessis +1

The availability of coherent sources of higher order Poincare optical beams have opened up new opportunities for applications such as in the optical trapping of atoms and small par…

Reply to Comment by K. Forbes on "The super-chirality of vector twisted light" by M. Babiker, J. Yuan, K. Koksal and V. E. Lembessis; Optics Communications 554, 130185 (2024)

M. Babiker, J. Yuan, K. Koksal +1

We respond to the recent comment in Optics Communications by Kayn Forbes on our recent Optics Communications article and we maintain that, contrary to what Forbes claims, substanti…

Direct Observation of the Faraday Rotation Using Radially-Polarized Twisted Light

Fatma Tambag, Koray Koksal, Fikret Yildiz +1

A novel experimental technique for the realisation of the optical Faraday effect using Laguerre- Gaussian (LG) light is described. The experiment employs a zero-order vortex half-w…

Super-chirality of paraxial higher order Poincare modes

Mohamed Babiker, Jun Yuan, Koray Koksal +1

We demonstrate that higher order Poincare modes of order m are super-chiral, displaying enhancement factors proportional to and in their helicity/chirality. With m having…

Optical properties of radially-polarised twisted light

Koray Köksal, Mohammed Babiker, Vassilis E. Lembessis

We show that, in general, any type of radially-polarised paraxial twisted optical mode carries only an axial total optical angular momentum (AM) …

Photo-Induced Image Current

Koray Koksal, Fatih Ahmet Celik

We study the possibility of the generation of the photo-induced image currents at a distance from the surface of nano-sized metal clusters by using time-dependent perturbation theo…

Chirality-enabled optical dipole potential energy for two-level atoms

Vassilis. E. Lembessis, Koray Koksal, Jun Yuan +1

We consider the optical dipole potential energy, which arises from the interaction of a two-level atom with a circularly polarized Laguerre-Gaussian laser beam of small waist. The…
