Broadband circularly polarized thermal radiation from magnetic Weyl semimetals

Congratulations to Yifan and Chinmay on their paper, “Broadband circularly polarized thermal radiation from magnetic Weyl semimetals” being published in Optical Materials Express. The paper demonstrates that a planar slab made of magnetic Weyl semimetal (a class of topological materials) can emit...

Edgy light on graphene may bring new one-way information routers

Purdue researchers have developed a “topological circulator” that may improve how information is routed and processed on a chip. Graphene has been the focus of intense research in both academic and industrial settings due to its unique electrical conduction properties. As the thinnest material known...

ECE student Ashwin Boddeti wins Wolf Outstanding Student Paper Competition

Ashwin Boddeti, a graduate student with Purdue University’s Elmore Family School of Electrical and Computer Engineering, has been awarded the Wolf Outstanding Student Paper Competition by Optica (formerly OSA). Established in 2008 to honor Emil Wolf for his many contributions to science and Optica...

CLEO Talks

Check out contributions from our group at the CLEO Conference. We had a series of exciting talks given by Xueji Wang, Farid Kalhor, and Ashwin Boddeti.

Bulk Properties of Topological Crystalline Insulators by Prof. Barry Bradlyn

Prof. Barry Bradlyn spoke about the discovery of topological materials as one of the most transformative recent breakthroughs in condensed matter physics, revealing new conceptual surprises in established topics such as the phases of matter and the behavior of electrons in insulators. Most work on...

A Dual Perspective On Inverse Design by Prof Sean Molesky

Prof Sean Molesky discussed how Lagrange duality heuristics for quadratically constrained quadratic optimization problems (QCQPs) can substantially lessen these knowledge gaps for a variety of common photonic design problems. As showcased by initial applications to topics including radiative...

Pico-electrodynamics by Dr. Sathwik Bharadwaj

Dr. Sathwik Bharadwaj spoke about the concept of photonic frequency (ω) - momentum (q) dispersion that has been extensively studied in artificial dielectric structures such as photonic crystals and metamaterials. However, the ω-q dispersion of electrodynamic excitations hosted in natural materials...
