PURPOSE: A multi-type optical waveguide, a light amplifier and an amplification method using the same are provided to form a light spot having high amplification rate comparison to an incident light. CONSTITUTION: In a multi-type optical waveguide, a light amplifier and an amplification method using the same, a metal layer(110) forms a C-type opening of a nano scale through which a light is passed. A dielectric layer(120) is combined in a metal layer which is arranged in the exit side of the C-type opening of a nano scale. |
