Abstract(in English) A photonic crystal fiber (PCF) can realize a flat dispersion in a wide wavelength range, which can not be realized in a conventional single-mode fiber. However, a confinement loss tends to increase in a conventional dispersion-flattened PCF, which has uniform air holes periodically. Moreover, it has not clarified that a characteristics of a dispersion-flattened PCF with both low confinement loss and enlarged effective area (A_). In this paper, we propose a novel PCF, which has two cladding layers with different effective indices with interval. We numerically clarify that a proposed PCF successfully achieves a flat dispersion with both low confinement loss and large A_.
