Nanophotonics Market Global Scenario, Market Size, Trend and Forecast

Nanophotonics Market Global Scenario, Market Size, Trend and Forecast

Nanophotonics or nano-optics is the study of the behavior of light on the nanometer scale, and of the interaction of nanometer-scale objects with light. It is a branch of optics, optical engineering, electrical engineering, and nanotechnology. It often (but not exclusively) involves metallic components, which can transport and focus light via surface plasmon polaritons.
