Abstract :
We investigate excitation and light collection from a scattering medium by an integrated waveguide probe. A probe with one excitation and eight collector waveguides is fabricated in silicon oxynitride technology. Experiments are performed on light collection from a highly scattering water suspension of latex nanospheres. By use of a Monte Carlo model, the propagation of light through highly scattering media is simulated and good agreement with the experimental data is found.
