Description
We present recent results on the design, fabrication and testing of multilayer optical haloscopes integrated with superconducting nanowire single-photon detectors for detecting bosonic dark matter particle candidates. In this scheme, we look for dark matter (such as dark photons) with rest mass energies in the range of meV to 10 eV. Highly uniform dielectric/semiconductor stacks are implemented with sufficient performance to enable sensitivity beyond existing experimental bounds near 800 meV. Optical metrology is performed to verify the uniformity of the stack across a 50 mm wafer. Furthermore, we show engineering solutions to facilitate reliable alignment between the optical system (comprising the dielectric stack, optical lens, and optomechanical components) and the superconducting detector. Finally, we consider future directions for improvements to the overall system.
Summary
We present recent results on the design, fabrication and testing of multilayer optical haloscopes integrated with SNSPDs for detecting bosonic dark matter particle candidates.
