摘要/描述

A dual-core photonic bandgap fiber (PBGF) is demonstrated byinfusing a high-index liquid into a dual-core air-silica photonic crystal fiber(PCF). Extremal couplings have been experimentally observed. Thetemperature tunable characteristics of the dual-core PBGF's bandgapguiding and dual-core coupling are experimentally and numericallyinvestigated. When we rise temperature, the dual-core PBGFs’ bandgapshave been changed: compression of bandwidth, blue-shift and depression ofthe guiding band. Especially, the dual-core coupling is temperature tunablebecause of the tunability of the infusion liquid’s index. We find that the riseof temperature increases the coupling length which results in the blue-shiftof the resonant peak wavelengths with a speed of 1.9nm/℃, for a 20mmdual-core PBGF.
