Abstract

Summary form only given. Supercontinuum (SC) light with a 400-1600 nm spectrum has been generated in optical fibres using unamplified femtosecond Ti:sapphire lasers. The fibre can be a special microstructure (photonic crystal) fibre with a core surrounded by large air holes, or it can be a standard telecommunications fibre that is tapered-narrowed by heating and stretching. In both cases, the waveguide is essentially silica (diameter ~2 μm) surrounded by air. The small diameter and large refractive index step give high intensities and desirable dispersion characteristics. We demonstrate SC generation in fused couplers made by tapering two fibres together
