Popis:	A novel octagonal photonic crystal fiber (O-PCF) with octagonal structure is proposed. The O-PCF has ultra-flattened dispersion and negligible loss characteristics throughout the third telecommunication window (1.55 mum to 1.7 mum). The design strategy to achieve these properties is based on optimization of tow air-hole diameters. The validation of the proposed design is carried out by employing a 2-D FDTD with perfectly matched layers. Macro-bending loss performance of the designed O-PCF is also studied. It is found that the fiber shows ultra-low loss, even in bends. Furthermore, octagonal structure advantages over triangular and honeycomb structure are proved.
