Collective Chiral Response of Achiral Plasmonic Arrays Induced by Truncated Bloch-Floquet Effect
Sahil Sahoo, Ahmed Lafeef Ettapuram Naduvilepurayil, Akash Das +1
Chirality in plasmonic systems is commonly associated with structures differentiated by their handedness. Here, we demonstrate the emergence of collective chirality in structurally…
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…
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…
