Single or close to single tunneling leaky modes have been prism coupled into nominally parabolic index SEL-FOC fibers with effective efficiencies on the order of 10%. The mode parameters fit fairly well to an analytical continuation of the solutions to Gloge and Marcatili's equations for parabolic index fibers. The data can also be used in conjunction with the Gloge and Marcatili equations to obtain information about the index profile.
单通道或接近单通道的隧穿泄漏模式已通过棱镜耦合到标称抛物线折射率的自聚焦光纤中，有效效率约为10%。模式参数与抛物线折射率光纤的格洛格和马尔卡蒂利方程解的解析延拓相当吻合。这些数据还可与格洛格和马尔卡蒂利方程结合使用，以获取有关折射率分布的信息。
