Thecoupling of a microsphere resonator to a tapered fiber wasdemonstrated at cryogenic temperatures (8 - 13 K) and investigatedwith a probe laser light whose frequency around the zerophonon line of nitrogen vacancy centers in diamond (638 nm).For this purpose, a liquid-helium-flow cryostat with a large samplechamber is developed and a resonance dip with a Qof 2 × 10⁶ is observed. The resonance frequency andthe coupling condition are found to be stable for aperiod of one hour. ©2010 Optical Society of America
