Abstract
We propose As2S3 slot waveguides, which have four zero-dispersion wavelengths and exhibit a flattened and low dispersion over a 1800-nm bandwidth from near-IR to mid-IR wavelength range. The dispersive wave generation is investigated based on this kind of dispersive profile by launching femtosecond pulses into As2S3 waveguides. Detailed simulations under realistic conditions show that considerable amount of dispersive wave emission occur in As2S3 waveguide and therefore can be desirable for optical communication and on-chip signal processing, such as frequency metrology, optical coherence tomography and microscopy.
