Directivity to improve optical devices

A team of researchers from the Dutch institute AMOLF, Western University (Canada), and the University of Texas (United States of America) recently demonstrated the use of algorithmic design to create a new type of nanophotonic ...

Graphene puts nanomaterials in their place

Nanomaterials offer unique optical and electrical properties and bottom-up integration within industrial semiconductor manufacturing processes. However, they also present one of the most challenging research problems. In ...

High-speed and on-silicon-chip graphene blackbody emitters

High-speed light emitters integrated on silicon chips can enable novel architectures for silicon-based optoelectronics. However, compound-semiconductor-based light emitters face major challenges for their integration with ...

Quantum leap in quest for digital speed and security

Society's increasing reliance on the internet, computers and mobile phones puts stringent demands on technological developments. Shrinking the electronic components – in other words, increasing the number of transistors ...

DNA origami lights up a microscopic glowing Van Gogh

Using folded DNA to precisely place glowing molecules within microscopic light resonators, researchers at Caltech have created one of the world's smallest reproductions of Vincent van Gogh's The Starry Night. The reproduction ...

Researchers transform slow emitters into fast light sources

Researchers from Brown University, in collaboration with colleagues from Harvard, have developed a new way to control light from phosphorescent emitters at very high speeds. The technique provides a new approach to modulation ...
