We demonstrate the first all-fiber mode-group-selective photonic lantern using multimode graded-index fibers. Mode selectivity for mode groups LP(01), LP(11) and LP(21)+LP(02) is 20-dB, 10-dB and 7-dB respectively. The insertion loss when butt coupled to multimode graded-index fiber is below 0.6-dB. The use of the multimode graded-index fibers in the taper can significantly reduce the adiabaticity requirement.
我们展示了首个使用多模渐变折射率光纤的全光纤模式组选择性光子灯笼。对于模式组LP(01)、LP(11)和LP(21)+LP(02)的模式选择性分别为20分贝、10分贝和7分贝。对接耦合到多模渐变折射率光纤时的插入损耗低于0.6分贝。在锥形结构中使用多模渐变折射率光纤可以显著降低对绝热性的要求。
