Reference Wavelength Free Refractometry in Fiber Optic Directional Couplers

Not Accessible

Your library or personal account may give you access

Abstract

Using dispersion management, opposite spectral shifts around the critical wavelength have been effectively removed. By operating the fiber-optic directional coupler based bio-sensor close to the critical wavelength, we report ultra-high refractive index sensitivity ∼13000 nm/RIU.
