Simulation on a dispersion-managed 4H-SiC on insulator waveguide for infrared supercontinuum generation.

Abstract

We demonstrate infrared supercontinuum generation in 4H-SiC on insulator slab waveguides. The effect of waveguide geometry parameters on dispersion is investigated to switch the zero-dispersion wavelength close to the pump wavelength. The 1cm long 4H-SiC waveguide is pumped by 100fs pulses at 1550nm with 2000W peak power, and the generated supercontinuum extends from ∼1000 to ∼3560n m (at 20dB level). This work shows that 4H-SiC has significant potential as on-chip photonic sources for spectroscopic applications in infrared wavelengths.
