Polarization-maintaining fused couplers are the key devices for coupling, splitting and multiplexing of linearly polarized light. Its biggest feature is that it can stably transmit two orthogonal linearly polarized light, and can keep their polarization states unchanged, so as to become a variety of military interference sensors, coherent optical communication, fiber optic gyroscopes and fiber optic hydrophones required key optical devices.
