Bandwidth steering in HPC using silicon nanophotonics [PDF]

Proceedings of the International Conference for High Performance Computing, Networking, Storage and Analysis, 2019
As bytes-per-FLOP ratios continue to decline, communication is becoming a bottleneck for performance scaling. This paper describes bandwidth steering in HPC using emerging reconfigurable silicon photonic switches. We demonstrate that placing photonics in the lower layers of a hierarchical topology efficiently changes the connectivity and consequently ...

Giant Magnetic Purcell Effect Induced by High‐Order Mie Resonances

Advanced Science, EarlyView.
High‐order Mie resonances in dielectric spheres selectively amplify magnetic dipole emission from Eu3+ emitters, producing a giant magnetic Purcell effect. Localized emitters can efficiently access high‐order resonant modes, and the low‐loss TiO2 platform enables direct far‐field observation of the enhanced emission.
