We report supercontinuum generation (SCG) in a dispersion-tailored bismuth-glass microstructured optical fibre. Simulations of near-infrared femtosecond pumping predict SCG spanning the near- and mid-infrared. Preliminary experiments show SCG from 0.8 μm to beyond 1.75 μm.

We propose a method for photonic crystal (PC) homogenisation based on the PC's Bloch modes. The resulting quantities may be used in Snell's law; to calculate reflections, transmissions, and propagation; and to locate surface modes.
