Stitch-Free, Diamond-Scribed Silicon Nitride Photonic Integrated Circuits for the Visible Band
Kishor Kumar Mandal, Lekshmi Eswaramoorthy, Parul Sharma +5
Silicon nitride photonic integrated circuits for the visible band are conventionally built with a buried oxide overcladding and singulated with wafer-scale tooling, constraints tha…
Magneto-optical intensity effect in a transparent perforated all-dielectric metasurface with an anapole state
Polina V. Zorina, Andrey N. Kalish, Vladimir I. Belotelov +2
We numerically study a perforated all-dielectric metasurface based on the magnetic semiconductor GaMnAs. Near the anapole state, the structure combines high transmittance with a mo…
Exceptionally high Verdet constant in gold nanodisc arrays
Gajendra Mulay, Shraddha Choudhary, Ashwin A Tulapurkar +4
Magneto-optical effects in non-magnetic noble metals can be greatly enhanced by leveraging the in-plane Lorentz force at engineered plasmonic resonances. We demonstrate a 2D array…
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…
Interplay of plasmonics and strain for Hexagonal Boron Nitride emission engineering
Anuj Kumar Singh, Utkarsh, Pablo Tieben +11
In the realm of quantum information and sensing, there has been substantial interest in the single-photon emission associated with defects in hexagonal boron nitride (hBN). With th…
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…
A low cost plasmonic platform for photon emission engineering of two dimensional semiconductors
Anuj Kumar Singh, Kishor K Mandal, Yashika Gupta +7
Although the field of 2D materials has democratized materials science by making high quality samples accessible cheaply, due to the atomically thin nature of these systems, an inte…
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…
Reflection confocal nanoscopy using a super-oscillatory lens
Arvind Nagarajan, L. Pjotr Stoevelaar, Fabrizio Silvestri +4
A Superoscillatory lens (SOL) is known to produce a sub-diffraction hotspot which is useful for high-resolution imaging. However, high-energy rings called sidelobes coexist with th…
