We have investigated the all-dielectric metasurface comprising the square array of nanodisks periodically arranged in two dimensions. The studies examined by performing the simulations determine the origin of the electric ...

We study the mesoscopic light transport and emission dynamics in a photonic structure made up of monodisperse scatterers as it undergoes an order-disorder structural transition. We have found a prominent tunable gaplike ...

We study the modification of spontaneous emission rate of nitrogen vacancy (NV) centers in nanodiamonds using photonic crystals. We discuss the spectral dependence of emission lifetime which give new insights into the ...

The propagation and emission of light in a real photonic crystal is routinely affected by the intrinsic disorder and its finite-size. Thus, theoretical calculation based on the notion of a defect free crystal with an ...

Dielectric metasurfaces with unique possibilities of manipulating light-matter interaction lead to new insights in exploring spontaneous emission control using single quantum emitters. Here, we study the stacked metasurfaces ...

In this article, we recount the scientific contributions of Dr Narinder Singh Kapany and the consequent advancements in optical fiber-based technology. He is acknowledged as the “man who bent light” and the first to coin ...
