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,

Applying implicit training to polarization-division-multiplexed coherent optical systems
Optics Express, 2013 We report the use of implicit training-aided channel estimation (ITA-CE) for polarization-division-multiplexed (PDM) single-carrier coherent optical systems. With the concept of ITA-CE, where the training sequence (TS) is arithmetically added onto the information symbols rather than appearing in separate time slots, overhead-free transmission can be ...

Four Wave Mixing-Based Time Lens for Orthogonal Polarized Input Signals
IEEE Photonics Journal, 2017 We present highly efficient time-lenses for orthogonal polarized signal waves with a specific state of polarization. Our four-wave mixing based time-lenses exploit polarization mode dispersion to compensate for chromatic dispersion.
