Abstract
An optical waveguide sensing method and device in which a waveguide layer receives an optical signal and propagates the optical signal in accordance with a predetermined optical waveguide propagation mode. A testing medium surface in communication with the waveguide layer is responsive to a testing medium for modifying at least one characteristic of the propagated optical signal in relation to a given parameter of the testing medium. In this manner, the modified characteristic of the propagated optical signal can be measured in view of determining the given parameter of the testing medium.
