An optical switch for single-mode fibers is presented. A novel polarizing prism is introduced to make the 2 input, 2 output optical switch insertion loss low and independent of the polarization state of the input fiber. This switch operates by one electric pulse with a voltage of only 2. 5 v and a current of 35 mA. The insertion loss was 1. 2 db, its fluctuation for different input polarizations was within 0. 03 db, and the far-end crosstalk was minus 26 db at a wavelength of 1. 3 mu m. The shock resistance of the switch was confirmed during an acceleration of 100 g.
