Abstract :
A guided-wave multi/demultiplexer which comprises low-loss gradient-index ion-exchange waveguides embedded in a glass substrate and optimised interference filters was successfully fabricated. Around ¿ 1dB insertion losses for demultiplexing and less than 2dB insertion losses for multiplexing with sufficient transmission bandwidth as wide as 66 nm were achieved.
