Abstract
A strip/slot hybrid waveguide with double horizontal silicon nanocrystals slots is proposed to achieve flat and low dispersion with four zero dispersion wavelengths. By tuning structural parameters of the waveguide, dispersion tailoring is fully characterized. The flat dispersion varying between -13 and 14 ps/(nm·km) is obtained over an 845nm bandwidth. A broadband supercontinuum spectrum, spanning from 1.15 to 3.65μm in the -15 dB level, was generated in this waveguide pumped by a femtosecond pulse at 1.86μm. Results indicate that the waveguide has great potential in near- and mid-infrared nonlinear applications.
