Magneto-Optics Increases Photonic Processing Efficiency for AI
A platform for in-memory photonic computing using magneto-optic material has the potential to offer efficient, nonvolatile data processing with unlimited read/write capabilities and sub-nanosecond programming speeds. The magneto-optic memory platform was developed by researchers from the University of California, Santa Barbara and several international institutions. It addresses multiple limitations of existing photonic processing techniques.

Snapshot Video Rate Hyperspectral Imaging Excels in Environmental Applications
Hyperspectral imaging combines the capabilities of imaging and spectroscopy in a single instrument, and is differentiated from traditional RGB imaging, which provides three channels of visible colors across an image. By contrast, hyperspectral imaging provides a complete spectrum with tens or even hundreds of bands, usually extending outside of the visible and in some cases even beyond the NIR band. It enables users to obtain valuable spectral information as a result, which can be used for image classifications, real-time detection, and surveillance.

Simulating Nano-Optical Scattering Efficiently
Thu, Mar 13, 2025 2:00 PM - 3:00 PM EDT
The clever design of optical scattering characteristics in nanostructures has become a fundamental building block for breakthrough devices in high-speed telecommunication, biosensors, solar cells, AR/VR, and more. Accurately describing and predicting this behavior calls for full-wave simulations. Justus Bohn demonstrates how to easily set up a simulation model through an example that focuses on single-particle scattering. Furthermore, the discussion extends to typical nano-optical structures, such as diffraction gratings, metasurface deflectors, plasmonic structures, photonic crystals, distributed Bragg reflectors, and hyperbolic metamaterials. Presented by COMSOL.
