An embodiment of an integrated waveguide is configured for reducing the level of Brillouin scattering, and for reducing the levels of at least some of the unwanted effects of Brillouin scattering. Such an integrated waveguide has a Brillouin gain, includes a cladding, and includes a core disposed within the cladding and configured to cause the Brillouin gain to be less than the Brillouin gain would be if the core were straight. For example, the core can be configured as a non-straight (e.g., meandering) core to reduce the Brillouin gain in an integrated waveguide, and, therefore, to reduce a level of coherent Brillouin scattering of an electromagnetic wave propagating through the waveguide. Therefore, a core so configured can reduce the energy of a counter-propagating Stokes wave induced by the propagating electromagnetic wave as compared to an otherwise comparable waveguide having a straight core.
