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.
