This can result in a splitting ofwavelength-dependent loss band and make the codirectional mode coupling condition (of the fundamental core mode into cladding modes) be different at two principal input polarizations.In a PM-LPG fabricated with a PMF having relatively small birefringence , the adjacent resonant dips (slow-axis and fast-axis resonant dips) resulting from the two principal input polarizations have identical cladding mode order and the wavelength separation between them is several nanometers

这可能导致分裂的ofwavelength-dependent损失，使codirectional乐队的耦合条件(模式基本核心人才培养模式为层模式)是不同的两种主要的输入波在PM-LPG捏造和具体情况有相对较小的双折射，相邻的谐振(slow-axis和fast-axis引起共振蘸)的两种主要模式有相同的输入波的波长层顺序和他们之间的分离是几奈米的图案
