Abstract :
A high-performance InP reflection-grating wavelength multiplexer for the 1530-1560 EDFA fibre band is reported. The 8 channel 3.6 nm-spacing devices operated with 30-35 dB channel isolation, <0.04 wavelength precision, and <10 dB on-chip loss. Although realised with 3.6 nm spacings, the multiplexer may be adapted for channels as close as 0.5 nm
