Wavelength-scale stimulated Brillouin scattering (SBS) waveguides are enabling novel on-chip functionalities. The microscale and nanoscale SBS structures and the complexity of the SBS waveguides require a characterization technique to monitor the local geometry-dependent SBS responses along the waveguide. In this work, we demonstrate an experimental spatial resolution of 500 μm, which can detect feature sizes down to 200 μm on a silicon–chalcogenide photonic waveguide using the Brillouin...[Show more]
