Сompensator of polarization mode dispersion based on spiral-wound single-mode fiber [PDF]
Tekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2013 A polarization mode dispersion (PMD) compensator for single-mode optical fiber has been designed. Its operation principle is based on the use of artificial difference of phase velocities of the basic ordinary and extraordinary waves in spiral-wound fiber,
