在低温（8 - 13 K）下，利用探测激光（638 nm）研究了微球谐振腔与锥形光纤的耦合。为此，我们研制了一个具有大样品室的液氦流低温恒温器，并观察到Q为2 × 10（6）的共振下降。共振频率和耦合条件被发现是稳定的一个小时的时间。
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-helium-flow cryostat with a large sample chamber is developed and a resonance dip with a Q of 2 x 10(6) is observed. The resonance frequency and the coupling condition are found to be stable for a period of one hour.
