Cr. Menyuk et Pka. Wai, POLARIZATION EVOLUTION AND DISPERSION IN FIBERS WITH SPATIALLY VARYING BIREFRINGENCE, Journal of the Optical Society of America. B, Optical physics, 11(7), 1994, pp. 1288-1296
A procedure is described that allows one to solve the evolution equati
ons in birefringent optical fibers by using repeated diagonalization.
With this approach several practical problems are solved in a unified
way. Included are evolution in twisted fibers, sinusoidally rocked fib
ers, and fibers with randomly varying birefringence. In the last case
it is shown that a phenomenological model described by Poole and other
s applies to fibers whose axes of birefringence can take on any orient
ation.
