What is Nanophotonics?

Nanophotonics is the study of light at the nanoscale level. It involves the interaction between light and matter, where matter can be any material that interacts with light. At the nanoscale level, materials exhibit unique optical properties that are not observed at larger scales. These properties arise due to the confinement of light in small spaces, which leads to enhanced interactions between light and matter.

How Does Nanophotonics Work?

Nanophotonics works by manipulating light at the nanoscale level using various techniques such as plasmonics, metamaterials, and photonic crystals. Plasmonics involves the interaction between light and free electrons in metals, while metamaterials are artificially engineered materials that exhibit unique optical properties not found in nature. Photonic crystals are periodic structures that manipulate light by controlling its propagation.
