Polarization-mode dispersion of a circulating loop

چکیده
We derive an analytic expression for the evolution of the differential group delay (DGD) in a fiber-optic circulating loop. We distill a simple analytic solution for the average DGD and show that it accumulates approximately linearly with transmission distance. The scaling of this linear function is confirmed experimentally using a long-haul fiber-optic transmission test-bed. This result is contrasted with DGD accumulation in a long straight-line transmission system, where the average DGD accumulates as a square root of the system’s length. © 2004 Optical Society of America OCIS codes: 060.2300, 060.2330, 060.2360, 060.5530.

Using a Recirculating Fiber Loop to Determine the Limitations Placed on Ultra-high-performance Soliton and Linear Optical Systems by Polarization Mode Dispersion
A short recirculating fiber loop (-100 km) that can emulate PMD with Maxwellianstatistics is realized by loop-synchronous polarization scrambling inside the loop. Theperformance of our distribution-correct PMD loop is compared both experimentally andnumerically to that of a distribution-incorrect PMD loop.©2000 Optical Society of AmericaOCIS codes: (060.2330) Fiber optics co...
متن کاملPolarization mode dispersion compensation of chirped Bragg gratings used as chromatic dispersion compensators
Compensation of Polarization Mode Dispersion (PMD) induced by a chirped Bragg grating is performed using a short length of highly birefringent fiber. A recirculating loop experiment demonstrates complete PMD compensation of the chirped Bragg grating. This simple method can be extended to deterministic PMD compensation of any components. Introduction: Pulse broadening induced by PMD is now an im...
متن کاملPolarization-mode dispersion of large mode-area photonic crystal fibers
We report on an experimental study of the polarization properties of large mode-area photonic crystal fibers (PCFs). We find that such fibers may exhibit very low birefringence and polarization-mode dispersion (PMD) indicating a highly symmetrical hole structure over a long length. Moreover, the influence of temperature on the polarization-mode dispersion is investigated. The results show that ...

متن کاملSolutions to the dynamical equation of polarization-mode dispersion and polarization-dependent losses
We study the evolution of optical signals in single-mode optical fibers in the presence of polarization-mode dispersion and polarization-dependent losses. Two geometric vectors on the Poincaré sphere are defined to characterize the effects of polarization-mode dispersion and polarization-dependent losses on the optical field in the fiber. By solving the dynamical equation for these two vectors,...
