Abstract
An optical sensor arrangement is provided. The arrangement comprises a light source coupled to an optical waveguide. The optical waveguide has at least one long period grating that promotes an excitation of confined propagating light into higher order modes causing an excitation of a sensing mechanism. A detector is coupled to the optical waveguide to detect a resulting optical signal.
