Paper Abstract

Investigation of liquid thin layers deposited on multimodal waveguide with gradient - index profile has been presented. Properties of the layers have been studied by the generalized m-line spectroscopy method. Deposited on the planar waveguide thin liquid layers have been investigated on the range refractive index 1.0002 - 1.5300. The profile of refractive index of waveguide has not been deformed because of depositing of the thin layer. Depositing of the thin layer on multimodal planar waveguide has caused the change of coupling angle to the waveguide but proportionately to successive modes of the waveguide structure. This study will be helpful to determine, for instance, illness changes of diabetic patients (sugar level in blood).
