Silicon is widely used in semiconductor industry for several optical applications but is also of great interest in optical applications. Especially in precision metrology applications, such as reference cavities or optical components in future gravitational wave detectors, it is currently of great interest. We summarize current efforts in order to investigate several optical parameters of silicon in a wide temperature range from 4.2 K up to 300 K.
