Optical sensor activation device |
摘要 |
An optical sensor having at least one long period grating disposed within an optical waveguide is provided. The optical waveguide has a refractive index profile. The long period grating has a plurality of index perturbations spaced apart by a periodic distance LAMBDA . The long period grating promotes an excitation of confined propagating broadband light into higher order modes that excite a sensing mechanism. The excitation of confined propagating broadband light is spectrally dependent on the periodic distance of the long period grating and the refractive index profile of the optical waveguide.
