Abstract

The coupling of a microsphere resonator to a tapered fiber was demonstrated at cryogenic temperatures (8 - 13 K) and investigated with a probe laser light whose frequency around the zero phonon line of nitrogen vacancy centers in diamond (638 nm). For this purpose, a liquid-heliumflow cryostat with a large sample chamber is developed and a resonance dip with a Q of 2 × 10 ⁶ is observed. The resonance frequency and the coupling condition are found to be stable for a period of one hour.
