Silicon as an optical material for precision applications at cryogenic temperatures — •Rene Glaser1, Stefanie Kroker2, Johannes Dickmann2, Carol B. Rojas-Hurtado2, and Ronny Nawrodt1 — 1Friedrich-Schiller University Jena, Institute for Solid State Physics, Helmholtzweg 5, 07743 Jena, Germany — 2Physikalisch-Technische Bundesanstalt, Metrology for Functional Nanosystems, Bundesallee 100, 38116 Braunschweig, Germany
Silicon is a promising candidate material for precision instrumentation applications such as laser stabilization cavities or future interferometric gravitational wave detectors. Here, applications benefit from the low opto-mechanical noise and its excellent thermal properties.
We present a systematic study of optical properties of silicon-based optical components and show the influence of optical properties on the metrological applications. The focus of our studies lies on properties at 1550 nm in a wide temperature range from 4.2 K to 300 K.
