A photonic integrated chip platform for interlayer exciton valley routing
Kishor K Mandal, Yashika Gupta, Mandar Sohoni +2
Interlayer excitons in two dimensional semiconductor heterostructures show suppressed electron-hole overlap resulting in longer radiative lifetimes as compared to intralyer exciton…
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…
A Broadband Dipolar Resonance in THz Metamaterials
Bagvanth Reddy Sangala, Harshad Surdi, Achanta Venu Gopal +1
We demonstrate a THz metamaterial with broadband dipole resonance originating due to the hybridization of LC resonances. The structure optimized by finite element method simulation…
Plasmonic quasicrystals for designable ultra broadband transmission enhancement and second harmonic generation
Sachin Kasture, Ajith P R, V J Yallapragada +4
Quasi-crystals are intriguing as they exhibit rotational symmetry and long range ordering but lack translational symmetry. 2-dimensional metal-dielectric patterns are interesting t…
Superluminal propagation and broadband omnidirectional antireflection in optical reflectionless potentials
L. V. Thekkekara, Achanta Venu Gopal, Sachin Kasture +2
Reflectionless potentials (RPs) represent a class of potentials that offer total transmission in the context of one dimensional scattering. Optical realization of RPs in stratified…
Nonlinearity Induced Critical Coupling
K. Nireekshan Reddy, Achanta Venu Gopal, S. Dutta Gupta
We study a critically coupled system (Opt. Lett., \textbf{32}, 1483 (2007)) with a Kerr-nonlinear spacer layer. Nonlinearity is shown to inhibit null-scattering in a critically cou…
