Abstract

AbstractWe have investigated a new design of hybrid microstructured optical fiber (HMOF) with chalcogenide glass core and tellurite glass cladding. We conducted the chromatic dispersion simulation and nonlinear coefficient calculation by using finite element method. The flattened dispersion with value between ‐20 and 32 ps/nm/km were successfully realized in wide wavelengths ranging from 1.5 to 3.8 μm and the nonlinear coefficient was 86000 km‐1W‐1, one or two orders lager than that of the highly nonlinear fibers reported so far. This HMOF exhibited promising features such as the low flattened dispersion property as well as high nonlinearity, which led to broadband optical amplification, wavelength conversion, and supercontinuum generation from near‐ to mid‐infrared region (© 2012 WILEY‐VCH Verlag GmbH & Co.
