| Abstract(in English) | Coupling characteristics of a photonic crystal fiber coupler (PCFC) depend on whether air holes at the tapered region of the PCFC are remaining or collapsed, and the characteristics of air hole collapsed PCFC depend on the length of air hole collapsed region. In this report, we proposed a new method for coupling characteristic adjustment of PCFC by air hole control using CO_2 laser irradiation after elongation process in coupler fabrication. It was clarified that the extinction ratio of PCFC could be successfully adjusted by air hole collapsing in the tapered region of air hole remaining PCFC and by controlling the length of air hole collapsed region using CO_2 laser irradiation. |
