摘要

An all-solid microstructured fiber containing a pure silica core and the double cross linear arrays of high refractive index dielectric rods imbedded in the silica serving as the cladding is proposed. The bandgap and confinement loss (CL) are numerically investigated. The fiber has a lowest loss of 3.37 dB/km that can be achieved in the first-order photonic bandgap (PBG) and the bandwidth with transmission loss less than < 0.05 dB/m is up to 550 nm. The effects of refractive index difference and geometric structure are discussed on the CL in the first-order PBG. The minimal attenuation can be reduced to 0.14 dB/km by choosing appropriate parameters. The bending property is also presented. (C) 2016 Optical Society of America
