title: Effect of depressed inner cladding on the polarization characteristics of elliptical-core fibers.
abstract: It is shown that by introduction of a depressed inner cladding in elliptical-core fibers, the birefringence can be increased and zero polarization-mode dispersion can be obtained within the single-mode regime. Further, as expected, the first-higher-mode cutoff is also increased.
