    摘要： Method for fabricating of all-optical-fiber based optical polarizer devoid of fusing of first and second optical fibers. The method includes a process of forming a substantially adiabatic optical fiber taper by pulling an optical fiber and interrupting this process when an optical power parameter measured at an output of the optical fiber is reduced below a pre-defined threshold as a result of said pulling. An optically-tapered single-mode polarization-maintaining optical fiber element fabricated according to the method and configured as such all-optical-fiber polarizer.
