Anisotropic fiber with a depressed-cladding profile.
Anisotropic fibers of the depressed-cladding type are analyzed by employing an iterative perturbation technique in a simple and straightforward way. An analytic expression is obtained for calculating the leaky-mode losses of an anisotropic depressed-cladding fiber. Numerical results show that such fibers possess much higher losses than those predicted earlier for a step-index model and hence are more advantageous for use in achieving singlepolarization, single-mode operation.
