<p>Thin and bright planar sources of light and linear sources of light cannot be obtained with the conventional art. According to this invention, a clad (8) is removed from an optical fiber (1), fine ruggednesses are formed on the surface of a core (9), a reflection film (2) is formed on the cross-section on one side thereof, and the cross-section on the other side is irradiated with a converged beam of light (6), thus realizing a fine linear source of light. A plurality of fine linear sources of light are arranged on a plane to realize a thin planar source of light. The invention further covers a method of using them. A thin and bright planar source of light can be utilized in various fields. </p> |
