We inscribe a Fabry-Perot (FP) resonator in the microfiber utilizing the 193-nm UV exposure and the phase mask technique. Some new characteristics including strong polarization dependence and large spectral dispersion in contrast to the conventional counterparts are measured, which are attributed to the two-fold symmetry of index change in the grating and the dispersion of the effective grating length, respectively. The thinner microfiber can generally generate stronger polarization dependence. The FP spectral dependencies on external strain, temperature, and refractive index are also investigated. Our fabricated structures can have potential of acting as photonic sensors or polarization related filters.
