title: Measurement of mode field radius in axially nonsymmetrical single-mode fibers with arbitrary power distribution.
abstract: A new method for the measurement of mode field radius in axially symmetrical and nonsymmetrical single-mode fibers with non-Gaussian power distribution is proposed. It is based on monitoring the power passed through a variable-width slit in the far field. A few results for different types of single-mode optical fiber are presented.
