4 December 1998 Tapered waveguide for broadband WDM optical dispersion compensation
Author Affiliations +
Mode conversion is used in a large refractive index difference tapered planar waveguide structure in order to obtain high negative dispersion (-1.5 to -200 ps/nm- cm) over 0.5 to 100 nm bandwidths. Light injected into a top silica core as a fast ARROW mode adiabatically converts into a slow conventional high-order mode of an underlying tapered silicon layer. The large differential velocity between the `redder' and the `bluer' spectral components of a pulse leads to dispersion compensation. Tailoring the profile of the silicon taper can compensate for higher-order dispersion in fibers.
