Quantum Optics + Quantum Foundations

Welcome to the website for our research group! We only recently began filling the page with content. Return here to keep up to date with the developments in our group. The image shows a 3D rendering of the design of a prototype for the high-finesse cavity that will eventually form the center-piece of the optical bench of the MAQRO space mission.

The baseplate is made from Silicon Carbide to provide optimal thermal stability at the cryogenic operating temperatures of MAQRO. All other components are made of fused silica. Light is coupled into and out of the cavity via a optical fibers. The light existing the fibers is focused into the cavity via off-axis elliptical mirrors, and the beam is folded via additional flat mirrors. The unprotected gold coatings minimize thermal emission and preserve the polarization of the light.
