title: Measurement of the wavelength dependence of beam divergence for photonic crystal fiber.
abstract: We report measurements of the wavelength dependence of beam divergence for single-mode photonic crystal fiber. These measurements confirm predictions of strongly wavelength-dependent beam divergence, consistent with the effective-index model for the photonic crystal cladding material.
