We consider a coupling system composed of a tapered fiber and a microsphere with gain. Power amplification and strong sensitivity to the absorbent sample molecule, on the surface of the sphere are found when gain is larger than intrinsic losses in this system. The intrinsic losses being in some extent compensated by gain make this system possess more advantage in integrated optics and photonics devices application.
