GaAs膜内注入载流子感生的折射率相对变化谱及其对光开关特性的影响

Relative refractive index variation spectra of a GaAs film and its effect on optical switch characteristic

实验测量了不掺杂GaAs膜内注入载流子感生的820～900nm波段反射率相对变化谱,从而得到对应的折射率相对变化谱,并分析其对光开关特性的影响。

The relative variation spectra of reflectivity induced by injected carrier in an undoped GaAs film at 820-900 nm rangs are measured experimentally. The relative variation spectrum of refractive index are also obtained using above results. The above results effect on optical switch characteristic are analyzed.
