Inverted Leakage Radiation Microscopy for measurement of nonreciprocity induced by a plasmonic metasurface with false chirality
Ahmed Lafeef Ettapuram Naduvilepurayil, Sahil Sahoo, Yuri Gorodetski
A system has a nonreciprocity when the light propagating through it in opposite directions encounters different optical adventures. This effect lies in the origin of various applic…
Basis-Independent Geometric Phase Modulation in Circularly Birefringent Plasmonic Structures
Pasha Goz, Akash Das, Andre Yaroshevsky +1
Geometric phase in metasurfaces is conventionally realized using spatially rotated linearly birefringent meta-atoms under circularly polarized illumination. Here we demonstrate tha…
Revealing Hidden Topology of Complex Vector Beams via Plasmonic Interactions
Sahil Sahoo, Ahmed Lafeef EN, Andre Yaroshevsky +2
Structured light beams with space-variant polarization can be efficiently generated using voltage-tunable nematic liquid-crystal (Q-plate). By appropriately selecting the input sta…
Spatio-Temporal Weak Measurement of Chiral Ultra short Laser Pulse
Sahil Sahoo, Andre Yaroshevsky, Dima Cheskis +1
We present a comprehensive study on the spatio temporal weak measurement of a chiral ultrafast optical pulse. We create a chiral vector wave packet by transmitting ultrashort laser…
