摘要：

A whispering gallery mode resonator with a pair of tapered optical fibers coupled to the surfaces of two microspheres is demonstrated. When the incident light is coupled to the two microspheres at the ends of a pair of tapered optical fibers via evanescent field, and the angle between the tapered fiber and the microsphere is appropriate, the whispering gallery mode of the two microspheres is excited. The device is simple in structure, easy in fabrication and low in cost and has a Q-factor of 1.3 x 10(4).
