Abstract
We demonstrate a hybrid integrated photonic-plasmonic platform in which photonic guided modes are used to efficiently excite localized surface plasmon resonance (LSPR) modes of plasmonic nanoresonators. Efficient coupling of light to the LSPR modes of plasmonic nanoresonators is demonstrated by tight integration of plasmonic nanoresonators on silicon nitride (SiN) microresonators. It is shown that by integrating gold nanoparticles with SiN microresonators, we can achieve high coupling efficiencies (>35%), resulting in large field enhancements. We will discuss the design, fabrication, and characterization of the hybrid platform which consists of gold nanoparticles integrated with SiN microring resonators.
