Abstract :
A large-scale arrayed-waveguide grating with a 400-channel and 25 GHz spacing using 1.5%-Δ silica-based waveguides on a 6-inch Si wafer has been realised. Good demultiplexing properties have been obtained over the full Cand L-band range with an on-chip loss of 3.8 to 6.4 dB and a far-end crosstalk of -30 dB
