Reference Wavelength Free Refractometry in Fiber Optic Directional Couplers (JW1A.84)
Presenter: Garima Bawa, IIT Kanpur
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 its critical wavelength, we report ultra-high refractive index sensitivity ∼13000 nm/RIU.
