Far-infrared multilayer mirrors

We present a concept for highly reflecting broadband mirrors in the far-infrared. We report on the fabrication of dielectric multilayer mirrors consisting of 1–6 layers of silicon wafers with vacuum gaps in between. By comparison to gold mirrors, we can demonstrate the high reflectivity (>99%) ov...

Description
Summary:We present a concept for highly reflecting broadband mirrors in the far-infrared. We report on the fabrication of dielectric multilayer mirrors consisting of 1–6 layers of silicon wafers with vacuum gaps in between. By comparison to gold mirrors, we can demonstrate the high reflectivity (>99%) over the frequency range between 40 and 130 cm−1. The measurements are in very good agreement with theoretical predictions.
