Abstract
The authors report high performance dense WDM multiplexers and demultiplexers with a 0.4 nm channel spacing. Special apodised fibre Bragg gratings (FBGs) and low loss bandpass WDM filters are utilised. The demonstrated cost effective eight-channel dense WDM devices have a high channel isolation of >25 dB and an insertion loss of ~7.5 dB. The WDM devices can be expanded to 32 or 64 channels in the same structures
