Abstract
Gamma ray radiation can change the refractive index of Ge-doped silica glass proportional to ray dose. These changes can shift the resonance frequencies of whispering gallery modes of microdisk. A fiber coupled microdisk has been used to design a Gamma-ray dose sensor. The 800MHz shift in resonance frequency of whispering gallery mode of microdisk, due to Gamma ray radiation has been used to detect Gamma dose in the range of 0 to 1MGy.
