“…8,9 Inspired by experimental observations, 10 Poole and Wagner introduced the concept of principal states, 11 which has been used widely in theory 12,13 and experiments. 14 Extensions of their concept account for polarization-dependent loss [15][16][17] and nonlinearity. 18 One of the most important problems, however, is how to compensate for PMD.…”

Periodic compensation of polarization mode dispersion

Polarization mode dispersion is the effect of signal broadening in a fiber with birefringent disorder. The disorder, frozen into the fiber, is characterized by the so-called vector of birefringence (VB). In a linear medium a pulse broadens as the two principal states of polarization split. It is well-known that, under the action of short-correlated disorder, naturally present in fibers, the dispersion vector (DV), characterizing the split, performs a Brownian random walk. We discuss a strategy of passive (i.e., pulse-independent) control of the DV broadening. The suggestion is to pin (compensate) periodically or quasi-periodically the integral of VB to zero. As a result of the influence of pinning, the probability distribution function of the DV becomes statistically steady in the linear case. Moreover, pinning improves confinement of the pulse in the weakly nonlinear case. The theoretical findings are confirmed by numerical analysis.

“…By the central limit theorem of probability, the second summation in (17) is approximately a Gaussian random variable with mean zero and standard deviation (22) in the case of sufficiently large . It is evident from (18) and (22) that the two sums in (17) have comparable contributions to the second-order correction. However, it is also clear that the second sum is a randomly fluctuation.…”

Abstract-In this paper, we develop a random-matrix formalism that enables analysis of a variety of polarization-mode dispersion (PMD) related problems. In particular, we address the problems of higher order error in a discrete fiber model and limit of multistaged PMD compensation schemes. Our solution to the first problem leads to a simple condition for the validity of the model, which is often overlooked in PMD simulations. For the second issue, we have found an asymptotic bound on the limit of a multistaged PMD compensation scheme. The theory is confirmed by numerical simulations, and future work is suggested.

“…As a result they are widely used in mid and short communication ranges, high power lasers and amplifiers, and in transporting high optical powers from one location to another [1,2]. Yet, while in single mode fibers the polarization dispersion is low and can be significantly reduced either by using polarization maintaining fibers or by operating at the principal state of polarization [3][4][5][6][7][8][9], in multimode fibers the mode dispersion is high resulting in significant reduction of performance [10,11]. Consequently, it is important to continuously analyze and monitor the dynamics of the modes propagating in multimode fibers.…”

Modal dynamics in multimode fibers

et al. 2012

The dynamics of modes and their states of polarizations in multimode fibers as a function of time, space, and wavelength are experimentally and theoretically investigated. The results reveal that the states of polarizations are displaced in Poincare sphere representation when varying the angular orientations of the polarization at the incident light. Such displacements, which complicates the interpretation of the results, are overcome by resorting to modified Poincare spheres representation. With such modification it should be possible to predict the output modes and their state of polarization when the input mode and state of polarization are known.
