New light source: A million times brighter than the sun

PhD thesis investigated application of a special white-light laser for semiconductor industry and microbiology

14-Feb-2022 - A new high-performance white-light laser is expected to speed up quality control in the semiconductor industry and provide closer monitoring of toxicity tests in microbiology. In one step, this laser enables the two-sided characterization of surfaces and can be integrated into production chains. ...

Bending light around tight corners without backscattering losses

Photonic crystal waveguide paves the way to build futuristic light-based computers

21-Nov-2018 - Engineers at Duke University have demonstrated a device that can direct photons of light around sharp corners with virtually no losses due to backscattering, a key property that will be needed if electronics are ever to be replaced with light-based devices. The result was achieved with photonic ...

A fast, non-destructive test for 2-dimensional materials

04-May-2017 - Thinning a material down to a single-atom thickness can dramatically change that material's physical properties. For example, graphene, the best-known 2D material, has unparalleled strength and electrical conductivity, unlike its bulk form, graphite. Researchers have begun to study hundreds of ...

New resource for optical chips

22-Feb-2017 - The Semiconductor Industry Association has estimated that at current rates of increase, computers’ energy requirements will exceed the world’s total power output by 2040. Using light rather than electricity to move data would dramatically reduce computer chips’ energy consumption, and the past 20 ...
