Abstract

This paper studies cross-polarized stimulated Brillouin scattering (XP-SBS) and its integration with quadratic nonlinearity in lithium niobate to enhance photonic device performance. Three novel applications are demonstrated: (1) a reconfigurable stimulated Brillouin laser with a 0.7-Hz narrow linewidth and 40-nm tunability, enabled by the thermo-optic phase matching of XP-SBS; (2) an efficient coherent mode converter achieving 55% conversion efficiency via intracavity Brillouin-enhanced four-wave mixing; (3) a Brillouin-quadratic laser and frequency comb operational in near-infrared and visible bands, benefiting from the interaction between XP-SBS and quadratic nonlinearity. These advancements promise substantial improvements in photonic technologies, including narrow-linewidth lasers, microcomb generation and optical signal processing, paving the way for more robust and versatile applications. Cross-polarized stimulated Brillouin scattering and its integration with quadratic nonlinearity is studied in lithium niobate, which enhanced photonic device performance in a reconfigurable stimulated Brillouin laser with 0.7-Hz narrow linewidth and 40-nm tunability, an efficient coherent mode converter, and Brillouin-quadratic laser and frequency comb operational in near-infrared and visible bands.
