| Abstract(in English) | Solid-core photonic bandgap fibers (SC-PBGFs) guide light along the fiber length in the low-index defected core region by the photonic bandgap (PBG) effect, where the transmission band properties are understood by the theory for ARROW waveguides. Due to its fibre-type functionality of alternate transmission and transmission-inhibited bands, the fiber can be applied to several filter devices. In general, SC-PBGFs suffer from the trade-off problem between the low bending losses and low confinement losses, because the use of 3rd PBG leads to low confinement losses while causing high bending losses. Exploiting 1st PBG, on the other hand, leads to low bending losses while causing high confinement losses. Moreover, reducing bending losses and realizing a single mode operation are also in the trade-off relation because the requirement of the large gap of the effective indexes between the core mode and the PBG floor to decrease the bending losses causes the higher-order-modes' guidance in general. In this work, we propose a novel concept of cladding structure which resolves the trade-off issues. The mechanism is based on the new concept of "heterostructured cladding". |
