<p><P>PROBLEM TO BE SOLVED: To provide a light emitting device using an optical fiber for greenly emitting a light of a shorter wavelength than the green light as an exciting light. <P>SOLUTION: The light emitting device has a light source 1 and an optical fiber 2 for propagating a light from the light source 1 having a peak wavelength in a range of less than 500 nm. The optical fiber 2 is made of an Er-doped fluoride glass. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
