A novel design of photonic crystal fiber with ultra-flattened dispersion and ultra-low loss

Abstract

A novel photonic crystal fiber (PCF) structure with triangular core is proposed. The PCF has ultra-flattened dispersion and negligible loss characteristics throughout the telecommunication windows (1.2 Jim to 1.7 pm ). The design strategy to achieve these properties is based on optimization of three air-hole diameters. Furthermore, the PCF has only seven rings of air-holes to control loss. 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 PCF is also studied. It is found that the fiber shows low bending losses for the smallest feasible bending radius of 5mm.

Design of Simple Structure Gas Sensor Based on Hybrid Photonic Crystal Fiber

“…Bo Li et al [30] proposed an octagonal multicore photonic crystal fiber structure with low confinement loss and good perspective for applications in high power propagation and others fields. Mohammad Nejad et al [31] proposed two types of OPCF (one is T-OPCF and another is H-OPCF) those are very suitable for near future applications.…”
