After a brief review of the existing 8-channel single-pole (first order) DEMUX, theoretical analysis suggested that the filter response could be improved by increasing the order of the filter from first to third, and with reduced losses from the microresonator and the bus waveguides. Device parameters were designed and optimized to meet the required system specifications. Experiments and progresses on the proposed 8-channel multi-pole (third order) DEMUX were presented. Preliminary results indicated an encouraging potential of the new design.... The initial values were set to Adisk(z-m)=0, Ahus(z-m)=l. The percent total power coupling coefficient was derived ... in a similar way. The results are shown in Figure 4.6. Figure 4.11 Schematic drawings of (a) a ridge-type waveguide and 88.
