Realizing negative index of refraction in an ensemble of ground-state polar molecules with lasers

Dibyendu Sardar, Sauvik Roy, Ghanasyam Remesh +2

We propose a coherent optical method for creating negative refractive index (NRI) for a gaseous ensemble of ground-state polar molecules possessing both permanent electric and magn…

Spectral singularity enhances transverse spin

Mounica Mahankali, Sudipta Saha, Nirmalya Ghosh +1

We study the transverse spin and the Belinfante spin momentum in a gain-loss balanced waveguide, known to be one of the first and most studied examples of -symmetric…

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…

Nonlinear Coherent Perfect Absorption

K. Nireekshan Reddy, S. Dutta Gupta

We review some of the recent concepts and their realization exploiting the perfect destructive interference of light in micro and nano structures. One refers to optical structures…

Giant Goos-Hänchen shift in Scattering: the role of interfering Localized Plasmon modes

J. Soni, S. Mansha, S. Dutta Gupta +2

The longitudinal and the transverse beam shifts, namely, the Goos-Hänchen (GH) and the Spin-Hall (SH) shifts are usually observed at planar interfaces. It has recently been shown t…

Two photon quantum interference in plasmonics - Theory and Applications

S. Dutta Gupta, G. S. Agarwal

We report perfect two photon quantum interference with near-unity visibility in a resonant tunneling plasmonic structure in folded Kretschmann geometry. This is despite absorption-…
