Evanescent wave — Schematic representation of evanescent waves propagating along a metal dielectric interface. The charge density oscillations, when associated with electromagnetic fields, are called surface plasmon polariton waves. The exponential dependence of… … Wikipedia
Evanescent wave coupling — In optics, evanescent wave coupling is a process by which electromagnetic waves are transmitted from one medium to another by means of the evanescent, exponentially decaying electromagnetic field. Coupling is usually accomplished by placing two… … Wikipedia

Superlens — A superlens, super lens or perfect lens is a lens which uses metamaterials to go beyond the diffraction limit. The diffraction limit is an inherent limitation in conventional optical devices or lenses.[1] In 2000, a type of lens was proposed,… … Wikipedia
Optical tweezers — (originally called single beam gradient force trap ) are scientific instruments that use a highly focused laser beam to provide an attractive or repulsive force (typically on the order of piconewtons), depending on the refractive index mismatch… … Wikipedia
Subwavelength-diameter optical fibre — A subwavelength diameter fibre wraps light around human hair. Subwavelength diameter optical fibre (SDF or SDOF) is an optical fibre whose diameter is less than the wavelength of the light being propagated through the fibre. An SDOF usually… … Wikipedia
