Abstract
Surface lattice resonance (SLR) lasers are promising for optical communication, optical computing, sensing and LiDAR applications. They have previously shown large-area single-mode emission with low threshold as well as tuneable spectral and angular emission using plasmonic nanoparticles embedded in thin film gain media. We demonstrate a novel device architecture with solid-state epitaxial InP gain medium that coupled to a gold nanoparticle array via a thin SiO2 layer. These plasmonic nanoparticles form SLRs that weakly couple to the InP waveguide mode forming a plasmonic-photonic hybrid mode supporting single-mode lasing with low thresholds. We experimentally and theoretically characterise the system. Our devices show no photobleaching. Combining plasmonic SLRs with epitaxial gain media paves the way for large-area on-chip integration of SLR lasers.
