| Abstract(in English) | A graded-index-type photonic crystal fiber (GI-PCF) that has α-power air hole diameter distribution in radial direction, where the area including holey cladding acts as a graded-index core. Hence, an application of GI-PCF to a collimator for single-mode photonic crystal fiber (PCF) can be expected similar to conventional graded-index-type multimode fibers. Since a beam diameter varied periodically along the propagation direction in the Gaussian beam excited GI-PCF, appropriate length of GI-PCF should be spliced to a single-mode PCF for the collimator application. In this report, variations of beam diameter in the GI-PCF were theoretically studied. It was clarified that the GI-PCF structure with small air hole diameter (small air hole diameter ratio to pitch) exhibited good tolerance in fiber length error. |
