Abstract
An improved model of wavelength division multiplexing (WDM) by superim posed gratings in planar waveguides has been developed. Based on this theory, principal design rules of N-channel WDM are established and a fanout capacity of 100 is estimated, Finally, four-channel WDM at 840 nm has been demonstrated on a Ge:SiO2/SiO2/Si planar waveguide, which was hydrogenated to enhance its photosensitivity. The superimposed gra tings were written using a narrow linewidth KrF excimer laser in an in terferometric setup used in inscribing fiber Bragg gratings.
