Optical fibre with fluorescent tip cap and methods of manufacturing

摘要

An optical component comprises: an optical fiber (7) having the core and the clad; a light guide holding member (1) attached to the exit end of the optical fiber; a wavelength conversion member (4) that contains a fluorescent substance; and a reflection means (5) provided between the exit end of the optical fiber and the wavelength conversion member, or between the light guide holding member and the wavelength conversion member. An increase in optical output is made possible not by reducing reflection as with conventional optical components, but on the contrary by actually producing reflection. Therefore, optical output can be increased by a means other than forming an optical film that reduces Fresnel reflection.
