Published in 2021 at "Optics Communications"

DOI: 10.1016/j.optcom.2021.126929

Abstract: Abstract We demonstrate the control of femtosecond single-filament formation via feedback-based wavefront shaping. It is observed that the optimal phase profile forms a single-filament with closed-loop genetic algorithm. Using this method, the position stability of… read more here.

Published in 2017 at "ACS Photonics"

DOI: 10.1021/acsphotonics.7b00346

Abstract: Custom plasmonic beams are advantageous for numerous scientific and technological aspects. While plasmonic wavefront shaping had traditionally been a truly planar process, taking place on a single surface, here we explore a new method for… read more here.

Published in 2022 at "Optics express"

DOI: 10.1364/oe.470194

Abstract: Aberrations and scattering limit the ability of optical microscopy to penetrate deep tissues. Adaptive optics (AO) is a very effective technique to correct for smooth aberrations. Wavefront shaping (WFS) techniques, on the other hand, compensate… read more here.
