Extended three dimensional optical tweezers with a Single Gaussian Beam in a stratified medium
Sramana Das, Suvajit Dey, Nirmalya Ghosh +2
We demonstrate a simple and effective approach for realizing extended volumetric optical trapping using a single linearly polarized Gaussian beam propagating through a stratified m…
Probing the Broken Spatial Symmetry of a Stratified Medium with Structured Light
Arani Maiti, Sauvik Roy, Nirmalya Ghosh +2
We study theoretically near-symmetric resonant stratified media to show how a tiny broken spatial symmetry can effectively be probed by structured light with or without orbital ang…
Tunable Optical Torque by Asymmetry-Induced Spin-Hall Effect in Tightly Focused Spinless Gaussian Beams
Sauvik Roy, Ram Nandan Kumar, Biswajit Das +3
A linearly polarized Gaussian beam, carrying zero net spin angular momentum, is conventionally not expected to exert optical torque or induce rotational motion in birefringent micr…
