摘要:

实验研究了氢化非晶硅纳米线的非线性特性。高非线性折射率n2=1.19 x 10-17 m2/W,结合低双光子吸收0.14 x 10-11 m/W,导致5.5的高非线性FOM。此外,在2.2W的脉冲峰值功率下超过数小时的操作时间的系统研究显示光学响应没有退化。

英文摘要:

The nonlinear characteristics of hydrogenated amorphous silicon nanowires are experimentally demonstrated. A high nonlinear refractive index, n2=1.19 x 10-17 m2/W, combined with a low two-photon absorption, 0.14 x 10-11 m/W, resulted in a high nonlinear FOM of 5.5. Furthermore, systematic studies over hours of operational time under 2.2W of pulse peak power revealed no degradation of the optical response.
