摘要
通过镁离子内扩散方法,实现了沿α轴向生长的掺镁钕铌酸锂单晶光纤具有阶跃和抛物折射率分布的芯-包层波导结构。对包层晶纤的损耗进行了测量,测得其损耗为1.80dB/cm,即比包层前晶纤损耗降低了约6倍。对包层晶纤的传输模式进行了观察,得到了低次模传输的好结果。
A core-cladding waveguide structure of the α-axis Nd:MgO:LiNbO_3 single crystal fiber with step and parabolic refractive indices profile is achieved by a Mg- ion indiffusion process. The loss coefficient of the cladded crystal fiber is measured and equals to 1.80dB/cm,which is six times as low as that of uncladded crystal fiber,Transmission modes of the cladded crystal fiber are also observed and low order modes are obtained.
