Query: Highly reflective low-noise etalon-based meta-mirror   We present a concept of a mirror for the application in high-reflectivity
low-noise instruments such as interferometers. The concept is based on an
etalon with a metasurface (meta-etalon) on the front and a conventional
multilayer stack on the rear surface. The etalon in combination with the
metasurface enables a dedicated spatial weighing of the relevant thermal noise
processes and by this a substantial reduction of the overall read out thermal
noise. We exemplary illustrate the benefit of the proposed etalon for thermal
noise in two applications: The test masses of the Einstein Telescope
gravitational wave detector and a single-crystalline cavity for laser frequency
stabilization. In the Einstein Telescope the thermal noise of the etalon even
at room temperature outperforms existing concepts for operation temperatures at
10K. For the laser stabilization cavity, a reduction of the modified Allan
deviation of an order of magnitude is predicted.
