Abstract:	Multimode silicon-oxynitride (SiON) waveguide structures are investigated for probing fluorescence and backscattered light from samples of different thicknesses. The collection efficiency together with the resolution of such probes is compared to that of a conventional fiber probe. The simulation results show that, in case of low scattering samples, among the two types of probes the former present higher collection efficiencies when the sample thickness is below 85 µm. The analytical model developed to estimate the collection efficiency of the integrated probes was validated experimentally through fluorescence measurements carried out on a ruby rod. The model and the experimental results are both presented in this work.
