我们考虑到在半人工材料中观察到的最大双折射效应。在电化学刻蚀（110）硅片制备的多孔硅薄膜中，在蓝-绿光谱范围内观察到大于0.7的平面内双折射。双折射薄膜在传感和偏振控制等领域有着广泛的应用。
We account the observation of the largest reported birefringence effect in a semi-artificial material. An in-plane birefringence of more than 0.7 was observed at the blue-green optical spectral range in a porous silicon film fabricated by electrochemical etching of a (110) Si wafer. Birefringent films are of interest in a variety of applications including sensing and polarization control.
