Reflectionless propagation of beams through a stratified medium
Sounak Sinha Biswas, Ghanasyam Remesh, Venu Gopal Achanta +3
Reflectionless potentials following the prescription of Kay and Moses allow for total transmission of incoming waves of any kinetic energy. The optical analogue of such potentials…
Doppler-assisted quantum resonances through swappable excitation pathways in Potassium vapor
Gourab Pal, Subhasish Dutta Gupta, Saptarishi Chaudhuri
We report the observation of two additional sub-natural line width quantum interference in the manifold of vapor, in addition to the usual single Electromagnetically…
Inhomogeneous spin momentum induced orbital motion of birefringent particles in tight focusing of vector beams in optical tweezers
Ram Nandan Kumar, Sauvik Roy, Anand Dev Ranjan +3
Spin orbit interaction (SOI) due to tight focusing of light in optical tweezers has led to exciting and exotic avenues towards inducing rotation in microscopic particles. However,…
Enhanced beam shifts mediated by Bound States in Continuum
Sounak Sinha Biswas, Ghanasyam Remesh, Venu Gopal Achanta +3
The interaction of light beams with resonant structures has led to the development of various optical platforms for sensing, particle manipulation, and strong light-matter interact…
Probing inhomogeneous and dual asymmetric angular momentum exploiting spin-orbit interaction in tightly focused vector beams in optical tweezers
Ram Nandan Kumar, Jeeban Kumar Nayak, Anand Dev Ranjan +3
The spin-orbit interaction (SOI) of light generated by tight focusing in optical tweezers has been regularly employed in generating angular momentum - both spin and orbital - in tr…
Transverse spin with coupled plasmons
Samyobrata Mukherjee, A V Gopal, S Dutta Gupta
We study theoretically the transverse spin associated with the eigenmodes of a thin metal film embedded in a dielectric. We show that the transverse spin has a direct dependence on…
