In this paper we report about design, deposition and measurement of the properties of nanocrystalline diamond (NCD) optical planar waveguides (OPW). The design of the presented planar waveguides was realized on the bases of modied dispersion equation and was schemed for 632.8 nm, 964 nm, 1310 nm and 1550 nm wavelengths. The NCD OPW was deposited by MWPECVD and the structure of the deposited lm was studied by SEM and Raman spectroscopy. Waveguiding properties were examined by prism coupling technique and it was found that the sample guided one fundamental mode. Values of the refractive indices of prepared NCD lm measured at various wavelengths were almost the same as those of natural diamond. Moreover, the decrease of diamond surface roughness by a formation of composite structure will be pointed out.
