摘要

We demonstrate the giant enhancement of stimulated Brillouin scattering in an As_2S_3 chalcogenide half suspended-core rectangle waveguide through simulation experiments. The half suspended-core waveguid is charactered by an effective length of 3.9 cm and a cross-section of 0.9 μm × 0.9 μm, which is supported by SiO_2 ridge glass. Through simulation experments, the Brillouin gain obtained is 54 dB for a pump power of just 248 mW. The 3-dB bandwidth can reduce to 8.2 MHz. A huge advantage of this structure is that it can obtain huge Brillouin gain and tiny 3-dB bandwidth for a low pump power and minute extension. This demonstration provides a feasible way for on-chip stimulated Brillouin scattering, which is important for microwave signal processing.
