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.
