Abstract
Design of an integrated optical tunable wavelength demultiplexer with a stable channel spacing is shown, utilizing software tools suitable for metal-clad diffused channel waveguides. The device, consisting on a three-mode depressed index waveguide with single-mode input and output waveguides has been designed using experimental data of double diffusion of MgO on Ti:LiNbO3 waveguides. The BPM simulations show the feasibility of the device, the stable spectral behavior and the narrow separation between channels obtained. It is also shown that the buffer layer between electrodes and waveguides can be eliminated depending on the design parameters
