The paper summarizes the experimental work carried out so far, involving investigations on the influence of the absorption of the planar waveguide cover on the attenuation of the guided modes - a phenomenon being a fundamental element of the functioning of optic sensors based on the effect of the absorption change of the cover. Theoretical fundamentals of this phenomenon have been discussed, a new measurement method has been presented.
