While nanocrystals offer color tunability and are used in various technologies, achieving different colors requires using different nanocrystals for each color, and dynamic switching between colors ...

Engineers are turning what used to be a bulky optics bench into something that fits on the tip of a finger, and the latest photonic chips go a step further by splitting a single laser into a ...

Toward developing chip-integrated and miniaturized nanophotonic devices, the incorporation of metasurfaces onto optical waveguides has attracted widespread attention as a compact platform for ...
