《Large-mode-area neodymium-doped all-solid double-cladding silicate photonic bandgap fiber with an index step of ～0.5%》
aTgis the glass transition temperature，Tsis the temperature at viscosity of 1×107.6d Pa·s，Tdis the general glass drawing temperature，andαis the thermal expansion coefficient at 100/300°C.
Four kinds of glasses were used to fabricate the fiber:the N0312 glass with an Nd doping level of 1.2 wt.%，and the undoped G1，G2，and G3 glasses.The N0312 glass was prepared by our laboratory，and the G1，G2，and G3 glasses were commercial silicate glasses provided by CDGM Glass Co.Ltd.The host compositions of the glasses are Si O2-Na2O-K2O-Ca O，and their thermal properties are shown in Table 1.The refractive indices of the N0312，G1，G2，and G3 glasses at 1064 nm are 1.5122，1.5123，1.5197，and 1.4614，respectively，measured by the V prism method with an accuracy of 5×10-5.
