ABSTRACT:
A method for correcting birefringence in a fiber optic coupler comprising measuring the intrinsic birefringent retardation, fast axis orientation and rotation of separate paths through the coupler and adding lumped birefringent elements to the ports of the coupler in a fashion to compensate for the intrinsic birefringence.
