In article number 1901680, Mahir Asif Mohammed, Oded Raz and co‐workers report on the metastable manipulation of the refractive index of hydrogenated amorphous silicon (a‐Si:H). Light‐induced increase of refractive index related to the increase of strain in the film is demonstrated which can be reversed by annealing. The finding would potentially find application in the field of programmable photonics and fine tuning of photonic devices to tackle fabrication‐related imperfections.

可重构光子学：用于可重构光子学的氢化非晶硅中的亚稳折射率操纵（高级光学材料6/2020）

Mahir Asif Mohammed，Oded Raz及其同事在编号1901680中报告了氢化非晶硅（a-Si：H）的折射率的亚稳态操纵。光致折射率的增加与薄膜应变的增加有关，这可以通过退火来逆转。这一发现有可能在可编程光子学和光子器件的微调领域中得到应用，以解决与制造相关的缺陷。
