In this paper, the use of tapered optical fibers with preservation of radiation polarization for the fabrication of microlenses is considered. The contraction of the fibers is achieved by stretching optical fiber under the influence of the  electric arc the splicing machine. This method allows to fabricate microlenses with a mode field diameter at the focal point of up to 2 μm and with a polarization extinction ratio (PER) coefficient of radiation at the output of the microlens of up to 40 dB. At the same time, the drop in the PER coefficient in the microlens is no more than 3 dB.
