Our recent theory work on the quantum commutation relations for the total angular momentum of light published in Journal of the Optical Society of America B. The total angular momentum of light has received attention for its application in a variety of phenomena such as optical communication...

On Thursday, December 12, 2024, the research of our group was featured at the Argonne National Laboratory's Materials Science Division/Hybrid Colloquium. Professor Zubin Jacob, Elmore Professor of Electrical and Computer Engineering (ECE) and Department of Physics, presented a talk titled...

A new paper authored by Leif and the research team, titled "Spintronic Bolometer for High-Sensitivity THz Detection," has been published in the journal Nano Letters. This publication presents a significant advancement in infrared detection technology. The work addresses the challenge of developing...

The gas turbines powering aircraft engines rely on ceramic coatings that ensure structural stability at high temperatures. But these coatings don’t control heat radiation, limiting the performance of the engine. Researchers at Purdue University have engineered ceramic “nanotubes” that behave as thermal antennas, offering control over the spectrum and direction of high-temperature heat radiation.

Congratulations to Fanglin Bao for his new paper in Optics Letters which talks about - Imaging point sources with low angular separation near or below the Rayleigh criterion are important in astronomy, e.g., in the search for habitable exoplanets near stars. However, the measurement time required to...

Over the past three decades, graphene has become the prototypical platform for discovering topological phases of matter. Both the Chern C ε Z and quantum spin Hall ν ε Z 2 insulators were first predicted in graphene, which led to a veritable explosion of research in topological materials. We...

Classical structured light with controlled polarization and orbital angular momentum (OAM) of electromagnetic waves has varied applications in optical trapping, bio-sensing, optical communications, and quantum simulations. However, quantum noise and photon statistics of three-dimensional photonic...

Our most recent work on "picophotonics" has been featured in Purdue News which says "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...

Our work on “picophotonics” has been featured in several leading scientific news outlets including optics.org and phys.org. Researchers at Purdue University have discovered new waves with picometer-scale spatial variations of electromagnetic fields that can propagate in semiconductors like silicon...

Our work on probing germanium plasmons through momentum-resolved EELS experiments got published in Optics Express. We reveal the metallic nature of Ge in the DUV regime. This new frontier of DUV plasmonics enables the development of DUV devices based on Ge. Read more about the paper here.
