PURPOSE: An apparatus for increasing intensity of a light source is provided to locally generate surface plasmon polariton resonance using a metal nano structure. CONSTITUTION: An apparatus(10) for increasing intensity of a light source(100) locally increases an electric field of an incident light source using surface plasmon polariton resonance. The apparatus for increasing intensity of the light source comprises the light source, a dielectric substrate(110), and a metal nano structure(120) on the dielectric substrate. The dielectric substrate is made of a transparent dielectric which is able to transmit incident light. The metal nano structure is composed of pairs of metals. The pairs of metals are regularly arranged on the dielectric substrate. The metal nano structure can be made of either gold(Au), silver(Ag), platinum(Pt), palladium(Pd), copper(Cu), silicon(Si), germanium(Ge), aluminum(Al), or a their mixture.
