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…

High precision micro-optical elements on fiber facets via focused-ion beam machining
Raman Kumar, Sebastian Will
Fiber-integrated micro-optical elements promise a scalable approach to photon collection and beam shaping for quantum information processing. Here, we demonstrate single-step micro…
