Nano Photonics

Nano photonics studies the behaviour of light on nano meter scales as well as interactions of nano meter sized objects with lights. Nano photonics is considered a branch of electrical engineering, optics, and optical engineering as well as being a branch of nanotechnology. Nano photonics includes metallic components that can transport and focus light through surface plasmon polaritons. One of the great promises of Nano photonics the possibility that light is trapped in optical cavities inside three-dimensional photonic band gap crystals. An optical cavity in a photonic crystal is manufactured by either adding or removing high index of refraction material, which yields a donor or an acceptor, respectively. The mirrors of the optical cavities are formed by the surrounding photonic crystal with a band gap. It has been predicted that light is trapped in such a photonic crystal cavity in a small volume as small as 1/100^th of a wavelength cubed. It is a challenge to embed such controlled point defects inside three-dimensional photonic band gap crystals to attain functional systems.
