Researchers have succeeded in making the thinnest ever optical device in the form of a waveguide just three atomic layers thick. The device could lead to the development of higher density ...

Optical biosensors and micromotors that can sense and actuate biological environments are considered promising theranostic devices because of their high spatial resolution and flexibility. Advancing ...

On-chip optical power monitors are indispensable for functional implementation and stabilization of large-scale and complex photonic integrated circuits (PICs). Traditional on-chip optical monitoring ...
