Your library or personal account may give you access

Abstract

We present the design and simulated characteristics of a highly sensitive refractive index sensor based on two coupled asymmetric strip waveguides with a top-loaded grating structure on one of the waveguides. The proposed sensor would be a on-chip device with a high sensitivity of ~ 1.5 × 104 nm/RIU.
