Digital equalization techniques for the compensation of nonlinear impairments in long-haul coherent optical communication systems
In 2008, the commercialization by Nortel of coherent optical communications digital transceivers operating at 40 Gb/s using Differential Phase Shift Keying (DPSK) revolutionized the field of fiber-optic communications because it provided superior spectral efficiency compared to the state-of-the-art …

Adaptive polarization mode dispersion equalizers for coherent optical communications systems
Polarization mode dispersion (PMD) arises as a result of the birefringence in optical fibers, due to inherent asymmetries and deformities from external stresses. The spectral components of the input optical pulse propagate with different group velocities. Consequently, pulse duration increases …
