The uniform twist of the birefringence axes of an optical fiber introduces a nonlinear nonreciprocity into power-dependent polarization switching characteristics. We experimentally demonstrate the nonreciprocity of a ten-beat-length-long twisted low-birefringence fiber that permits all-optical logic operations with orthogonal circularly polarized input pulses.
