Fano resonance ion sensor enabled by 2D plasmonic sub-nanopores-material

Silicon photonics has shown great potential in integrated biochemical sensing. However, it is challenging to detect ions selectively, which is crucial in several biochemical application. In this paper, we propose and demonstrate a newly designed ion sensor by combining two-dimensional (2D) plasmonic and sub-nanoporous KxMoO3 with a silicon waveguide. A T-shaped waveguide coupled with a microring r...
