Abstract
The present invention relates to an optical sensor adapted to measure at least three physical parameters, said optical sensor comprising a polymer-based optical waveguide structure comprising a first, a second and a third Bragg grating structure. The first, second and third Bragg grating structures are at least partly spatially overlapping in the polymer-based optical waveguide structure and thereby form a compact sensor structure. The invention further relates to a method for measuring the first, the second and the third physical parameter, and a method for manufacturing the optical sensor.
