Tunable splitting ratio of optical fiber ring resonator for sensing application

摘要

We investigate three conditions of optical fiber ring resonator. The tunable central light intensity of ring resonator can be realized through adjusting the dynamic variation of splitting ratio on the conditions of over-coupling, under-coupling and active-coupling. Especially in active-coupling case, we can get the large intensity at the resonant frequency with increase in splitting ratio in smaller range. This property can be used for sensing application and other fields.
