We have simulated the transmission spectra for the tapered fibers with no, one and two deformations in the visible wavelength range by Finite-Difference-Time-Domain method. The transmission peak positions shift to the shorter wavelength and the intensity changed to be larger, when the taper is added to the fiber or the taper deformation changed to be larger. The deform sensitivity for the tapered structures with different taper diameter is about 1.59e-3 nm·𝜇m-1. The interference structure is apparent in the electric field distributions and there is apparent interference stripes in the interference structure. The transmission spectra for the tapered fiber immersed in different refractive media are present. The refractive sensitivity for the fiber with two deformation is about 50 nm/RIU and for the one tapered fiber is about 12.3 nm/RIU. The visible tapered fiber can be extensively applied to the bio-chemical sensor and physical test and so on..
