In this work, the double-cladding (DC) structure dependence of guiding characteristics in six-fold symmetric photonic quasi-crystal fiber (PQF) is investigated. Three PQFs featuring one, two and three rings of inner air holes are considered. Numerical results show that with the increase of inner air...
