我们展示了正方形Ge 11.5As 24 Se 64.5（Ge 11）非线性纳米线的设计和制造完全嵌入在二氧化硅包层的偏振无关（P-I）非线性处理。我们观察到类似的性能，四波混频使用TE和TM模式确认，近P-I操作获得。此外，我们还发现，在纳米线中使用峰值功率约为30 W的1 ps脉冲可以产生与偏振无关的超连续谱。
We demonstrate the design and fabrication of square Ge11.5As24Se64.5 (Ge11) nonlinear nanowires fully embedded in a silica cladding for polarization independent (P-I) nonlinear processing. We observed similar performance for FWM using both TE and TM modes confirming that a near P-I operation was obtained. In addition we find that the supercontinuum spectrum that can be generated in the nanowires using 1ps pulse pulses with around 30W peak power was independent of polarization.
