Paper Abstract

In this work, two kinds of strip/slot hybrid As2S3 waveguides with the silicon dioxide slots, which are demonstrated to have low and flat dispersion profiles are proposed. Based on those waveguides, we obtain broadband and highly coherent supercontinuum numerically using the nonlinear Schrödinger equation. For the waveguide with a vertical silicon dioxide slot, the dispersion between ±20 ps/(nm∙km) from 1435 to 2800 nm is obtained by adjusting the structure parameters. The broadband spectrum covering from 1392 to 2916 nm at -35 dB level is generated in a 5.5-mm waveguide with high correlation of ~1. For the waveguide with a horizontal silicon dioxide slot, the dispersion spans ±4 ps/(nm∙km) from 1685 to 2770 nm and the generated spectrum with correlation of ~1 spans from 1212 to 3979 nm in a 5.5-mm waveguide.
