摘要：
We realize a microdroplet-etched fiber Fably-Perot resonator. Strong polarization discrimination is achieved due to the asymmetric fiber cross section in the cavity, which should be useful for improving the measurement precision in the refractive index (RI) sensing application. The measured RI sensitivities are similar to 133.8 nm/RI-unit for the x polarization and 117.1 nm/RI-unit for the y polarizations, respectively. Simultaneously, the temperature effect can be eliminated by monitoring the peak difference of the two polarizations, which have the similar temperature coefficient but different RI responses.
