Light Scattering from Contamination and Defects - Measurement, Analysis, and Modelling [PDF]

open access: yesEPJ Web of Conferences, 2022
Light scattering induced by contamination and defects on optical components can quickly limit the component’s performance. Therefore, imperfection analysis and budgeting are mandatory - but also challenging tasks.

Optical Kerr nonlinearity of dielectric nanohole array metasurface in proximity to anapole state [PDF]

open access: yesOptics Letters Vol. 47, Issue 11, pp. 2866-2869 (2022), 2022
Metasurfaces have attracted a great deal of attention from researchers due to their prominent optical properties. In particular, metasurfaces may consist of structures possessing optical anapole resonances with strong field confinement and substantially suppressed scattering.

Magnetorheological method applied to optics polishing: A review

open access: yesIOP Conference Series: Materials Science and Engineering, 2020
Magnetorheological finishing method is carried out in order to correct errors of figures which are produced by conventional polishing methods on planes, spheres, aspheres and freeform optics having surface roughness value as low as 1 nm RMS.

Ultralow-power all-optical switching via a chiral Mach-Zehnder interferometer [PDF]

open access: yes, 2021
All-optical switching increasingly plays an important role in optical information processing. However, simultaneous achievement of ultralow power consumption, broad bandwidth and high extinction ratio remains challenging. We experimentally demonstrate an ultralow-power all-optical switching by exploiting chiral interaction between light and optically ...

Tapered multicore fibers for energy-scalable fiber laser systems [PDF]

open access: yesEPJ Web of Conferences, 2022
With active multicore fibers (MCFs), many parallel amplifying waveguides can be densely assembled into a common glass cladding. A tapered fiber geometry applied to MCFs enhances the power and energy scalability of these systems by increasing the doped ...
