Prof Zubin Jacob gave a plenary talk at the physics of quantum electronics conference. He spoke about the recent theory work on Atomistic Maxwell Hamiltonians and the topological optical-N insulator.

Our first speaker was a pioneer in the field of theoretical quantum optics - Prof. John Sipe from the University of Toronto. He talked about the response of solids to incident electromagnetic fields which is often heuristically described in terms of macroscopic polarization and magnetization fields...

Published in PR Applied, our recent work develops the theoretical and computational framework to analyze the spin angular momentum of thermal radiation from bodies with nonuniform temperature profiles. By considering a sample problem of a long silica wire held under a temperature gradient within its...

Wenbo Sun received the Outstanding Graduate Student Research Award in recognition of his excellence in graduate student research. The award was conferred at the Purdue College of Engineering Graduate Education Awards 2024 luncheon on April 17th, . This is awarded to 13 Ph.D. students (2 from ECE)...

Prof. Zubin Jacob, Elmore Professor of Electrical and Computer Engineering is the latest guest on the Episode 3 of "Engineering Innovations", the official podcast of Purdue ECE. He talks about his path to engineering, his current research, and what he thinks is ahead for the field. Listen here...

We discuss the engineering of the spatial and temporal properties of both the electric permittivity and the refractive index of materials is at the core of photonics. When vanishing to zero, those two variables provide efficient knobs to control light–matter interactions. This Perspective aims at...

Light-matter interaction in materials is central to several photonic devices from lasers to detectors. Over the past decade, nanophotonics, the study of how light flows on the nanometer scale in engineered structures such as photonic crystals and metamaterials has led to important advances. This...

Check out our recent News & View article ‘Symmetry breaking in thermal photonics.’ in Light: Science and Applications. Thermal radiation is omnipresent and is engineered for various applications in modern photonics, such as cooling, imaging, and energy harvesting. Symmetries and symmetry breaking...

A new approach to control forces and interactions between atoms and molecules, such as those employed by geckos to climb vertical surfaces, could bring advances in new materials for developing quantum light sources.

A newly described property related to the "spin" and momentum of light waves suggests potential practical applications in photonic communications and photonic circuits. Scientists already knew that light waves have an electric field that can rotate as they propagate, which is known as the polarization property of light, and that light waves carry momentum in their direction of motion. In new findings, researchers have discovered a "spin-momentum locking," meaning, for example, light waves that spin in a counterclockwise direction can only move forward, and vice versa.
