Subwavelength grating bimodal waveguide for refractive index sensing

Not Accessible

Your library or personal account may give you access

Abstract

Periodic subwavelength structures supporting two TE modes are presented as high performance sensors with bulk and surface sensitivities of 1375.5nm/RIU and 6.138nm/nm, respectively. A complete theoretical study is provided by numerical expressions and FDTD simulations.
