Paper Abstract

A systematic study on integrated wavelength multi/demultiplexers is presented, in which the experimental features of the devices, the theoretical predictions of a simple model, and the results of extensive modelling by a BPM analysis are compared. The components are based on the two-mode interference principle, and are fabricated on soda-lime glass by Ag-Na ion exchange. The modelling is performed by CAOS, a user-friendly general purpose simulator, based on a FD scheme with transparent boundary conditions. The agreement between experimental and simulated spectral characteristics is very good; moreover the proposed analysis procedure allows the determination of the maximum index variation (Delta) n and the diffusion depth D which describe the optical and geometrical characteristics of the waveguides.
