| Outline of Final Research Achievements |
A photonic crystal fiber (PCF) has periodically arranged air holes in its cross section. As a method for light coupling from a light source to the PCF, we proposed a GI-PCF collimator in which a GI-PCF with alpha-power air hole diameter distribution in radial direction is spliced to the PCF. GI-PCF structures to obtain high optical coupling efficiency to the PCF were clarified, and a prototype of GI-PCF was designed and fabricated. It was also clarified that a GI-PCF was effective for loss reduction in PCF splicing with gap.
