摘要 对芯层为负折射率介质,包层为普通介质的光纤的导模进行了研究,并对TM模中出现的TM00模进行了详细的分析。此模可能存在具有相同的纵向相移常数β和不同的横向相移常数T的两支特殊的简并模式。此外,对出现这种特殊简并模式的条件进行了讨论,并分析了此特殊模式的色散特性。 The guided modes in a step index fiber formed by a core with negative index and a usual dielectric cladding are numerically investigated, and a special guided mode called TMoo mode can exist in TM modes. There are special double degenerate modes which have same longitudinal propagation constant β and different transverse propagation constant T in the TMoo mode. The condition of the special double degenerate modes is analyzed, and the dispersive characteristics of these modes are analyzed in detail.
