Abstract
Recent developments in quantum light–matter coupled systems and quantum
transducers have highlighted the need for cryogenic optical
measurements. In this study, we present a packaged fiber-optic coupler
with a coupling efficiency of over 50% for telecom wavelength light
down to the mK temperature range. Besides the high coupling
efficiency, our method enables sensitive photonic device measurements
that are immune to mechanical vibrations present in cryogenic
setups.
