Dynamics of Light Localization via Coherent Control: The Interplay of Transmission, Absorption and Disorder in Photonic Crystals
Nancy Ghangas, Ghanasyam Remesh, Venu Gopal Achanta +1
This study investigates the interplay between structural disorder, absorption, and Lyapunov exponent dynamics to exploit localization phenomena in photonic crystals with engineered…
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…
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…
Diffraction of an Off-axis Vector-Beam by a Tilted Aperture
Ghanasyam Remesh, Athira B S, Shyamal Gucchait +3
Manifestations of orbital angular momentum induced effects in the diffraction of a radially polarized vector beam by an off-axis tilted aperture are studied both experimentally and…
Exploring the route from leaky Berreman modes to bound states in continuum
Ghanasyam Remesh, Pravin Vaity, Venu Gopal Achanta +1
We study coupling of leaky Berreman modes in polar dielectric films (SiO2) through a thin metallic layer (gold) and show the familiar signatures of normal mode splitting. Due to ve…
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…
