I guess you are simulating 3D CHARGE. Do you also use 3D FDTD result when the Ge width changes? if the imported light absorption does not change with width, meaning you import 2D data after integration in 3rd dimension, then your electric simulation in CHARGE will not change. Please check.

BTW: Lumerical's ALF is in Photonics category here: https://forum.ansys.com/index.php?p=/categories/photonics you can either post questions in the English forum, or in other languages such as Chinese and Korean.
