Abstract
A self-emitting optical probe having a built-in light-emitting function, wherein the light-emitting mechanism and the aperture portion of the optical probe are formed by depositing an electrically conductive thin film, an organic thin film, and a metallic film by means of sputtering and oblique vacuum evaporation while rotating the core. The self-emitting optical probe enables an inexpensive scanning near field optical microscope yet simplified in operation.
