Potential Due to a Polarized Object

Potential Due to a Polarized Object

A neutral atom consists of a positively charged nucleus surrounded by a negatively charged electron cloud. When placed in an external electric field, the external electric force pulls the electrons and nucleus apart, opposite to the intrinsic attraction between the nucleus and the electrons. The opposing forces balance each other with a slight shift between the center of masses of the nucleus and the electron cloud, resulting in a polarized atom. On the other hand, a few molecules, like water,...

Area of Science:

Photonics and Nanophotonics
Materials Science
Optical Engineering

Background:

Metamaterials and plasmonic structures offer unique light-matter interactions.
Achieving high absorption and polarization control in thin films remains a challenge.

Purpose of the Study:

To introduce and characterize resonant absorbers based on metal-dielectric nanostructures.
To demonstrate their potential for high absorption and optical filtering applications.

Main Methods:

Fabrication of titanium dioxide gratings with embedded linear metal wires using electron beam lithography and atomic layer deposition.
Optical characterization of absorption, contrast, and extinction spectra.

Main Results:

Achieved near-total absorption (99.67%) for a specific polarization at 532 nm.
Demonstrated high contrast (6600) and extinction (8.8597).
Observed enhanced absorption due to guided-mode resonance and localized surface plasmon resonance.

Conclusions:

The proposed resonant absorbers exhibit exceptional performance in a compact form factor.
These structures show significant potential as efficient optical filters and polarizing beamsplitters.
