Abstract

Love wave sensors have attracted significant attention due to their high sensitivity and compatibility with liquid environments for biosensing applications. However, conventional waveguide designs face challenges including thick film requirements (2%–11% wavelength), complex multilayer processing, and film delamination issues. Here, we demonstrate a dual-layered SiO2/Cr/Au/Cr waveguide structure that achieves enhanced performance with dramatically reduced thickness (
