摘要：
We present and analyze a novel hollow-core photonic quasi-crystal fiber (HC-PQF) constructed with 12-fold quasi-periodic structure. The quasi-periodic cladding is shown in this letter to be able to guide light in a large-size hollow core. This HC-PQF provides two photonic bandgaps in the lambda/Delta < 1 region, thus two spectral windows of low loss guidance can be achieved. The behavior of guided modes that depends on the size of the defect core is studied, and the dispersion and confinement loss are also investigated. This research gives a physical insight into the propagation mechanism in HC-PQF and is crucial for future transmission applications.
