Abstract: Photonic transport facilitated by topological protection is a proposed advantage of photonic topological waveguides based on valley photonic crystals (VPCs). Although topological protection significantly suppresses backscattering in these waveguides, it is often desirable to achieve… read more here.

Abstract: Stimulated Brillouin scattering (SBS) provides a robust and versatile foundation for the development of mode-locked lasers, microwave signal generators, and optical gyroscopes across diverse optical platforms. Nonetheless, the relatively low efficacy of Brillouin interactions in… read more here.
