Robust SiON rib waveguides for CMOS-compatible surface plasmon resonance sensing of aqueous analytes
Silicon oxynitride (SiON) is a highly adaptable material platform for photonic integrated circuits owing to its refractive index tunability and full CMOS compatibility. In this work, an integrated surface plasmon resonance (SPR) sensor based on a robust SiON rib waveguide is demonstrated. The sensor geometry and moda...
