| Abstract: | A guided-wave optical waveguide-division multi/demultiplexer for bidirectional transmission at (0.81 ?m, 1.2 ?m)/(0.89 ?m, 1.3 ?m) wavelengths has been realised using high-silica channel waveguides on silicon substrate. The multi/demultiplexer connected with graded-index multi-mode fibres shows a loss of 3.5?5 dB together with far-end and near-end crosstalk levels less than ?30 dB and ?50 dB, respectively. |
