Abstract

Chalcogenide nanostructures are an interesting platform for ultra-fast nonlinear signal processing. However, stimulated Brillouin scattering (SBS) can represent a major obstacle to achieving this goal for continuous wave pumps, as it depletes the high-power pump wave. In this paper, we assess the SBS gain in an As2Se3 nanowire, which is found to be much larger than the SBS gain in As2Se3 fibers. Such a large SBS gain poses a severe problem, and standard concepts for fibers, such as Bragg gratings and tapers are found not to work for nanowires. However, through the introduction of an amorphous polycarbonate cladding, the elastic modes and the optical mode can be separated, and SBS can thus be efficiently suppressed by three and a half-orders of magnitude. At the same time, flexibility for other design goals, such as phase matching, is maintained.
