Tailoring radiation pressure on infinite slab using pair of non-collinear plane waves
R. Ali, R. S. Dutra, S. Iqbal
The electromagnetic field exerts radiation pressure on the matter and tends to move it either in the backward or forward direction due to net optical pulling or pushing force, resp…
Enantioselective optical forces in gain-functionalized single core-shell chiral nanoparticles
R. Ali, F. A. Pinheiro, R. S. Dutra +2
We propose a gain-assisted enantioselective scheme in dye-doped chiral particles, demonstrating optical pulling and pushing forces that can be tuned using externally controllable p…
Lighting of a monochromatic scatterer with virtual gain
R. Ali
In this work, we discuss the scattering features of a dipolar particle made of large refractive index material by employing the concept of virtual gain and virtual loss. The virtua…
Gain-assisted optical tweezing of plasmonic and large refractive index microspheres
R. Ali, R. S. Dutra, F. A. Pinheiro +1
We have theoretically investigated optical tweezing of gain-functionalized microspheres using a highly focused single beam in the nonparaxial regime. We employ the Mie-Debye theory…
Enantioselection and chiral sorting of single microspheres using optical pulling forces
R. Ali, R. S. Dutra, F. A. Pinheiro +1
We put forward a novel, twofold scheme that enables at the same time all-optical enantioselection and sorting of single multipolar chiral microspheres based on optical pulling forc…
Theory of optical tweezing of dielectric microspheres in chiral host media and its applications
Rfaqat Ali, R. S. Dutra, F. A. Pinheiro +2
We report for the first time the theory of optical tweezers of spherical dielectric particles embedded in a chiral medium. We develop a partial-wave (Mie) expansion to calculate th…
