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...
EXPLOITING LOSS
Metamaterials operating at frequency ranges in which the dielectric permittivity is close to zero have been discussed for use across a wide range of optical applications. Sean Molesky and colleagues from the University of Alberta in Canada, have now proposed methods for engineering thermally excited...
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...
Electron Energy Loss Spectroscopy
Strong nanoscale light–matter interaction is often accompanied by ultraconfined photonic modes and large momentum polaritons existing far beyond the light cone. A direct probe of such phenomena is difficult due to the momentum mismatch of these modes with free space light, however, fast electron...
Electron g-factor engineering for nonreciprocal spin photonics
P. Sengupta, C. Khandekar, T. Van Mechelen, R. Rahman, and Z. Jacob, “Electron g-factor engineering for nonreciprocal spin photonics”, Physical Review B, vol. 101, no. 3, p. 035412, 2020.
Emil Wolf Outstanding Student Paper Competition
Congratulations to Ashwin Boddeti on his selection as a finalist for the Emil Wolf Outstanding Student Paper Competition at FIO2021 for the paper titled: Giant Long-Range Dipole-Dipole Interactions in a Plasmonic Lattice in the FiO 3 Quantum Electronics category. The paper talks about the...
