<P>PROBLEM TO BE SOLVED: To provide a light emitter of fiber shape that achieves miniaturization and thin wire, and to provide a light emitting device using the same. <P>SOLUTION: The light emitter has a core section containing a light emitting material which absorbs excitation light and emits light with a wavelength longer than the excitation light, and a clad section which is installed at the outside of the core section and in which a plurality of second regions having a higher refractive index than a first region are periodically formed in the first region having a refractive index same as or more than the core section, and has a fiber shape. Further, a light emitting device using the light emitter is provided. <P>COPYRIGHT: (C)2012,JPO&INPIT |
