Abstract :
The crosstalk of arrayed-waveguide grating (AWG) multi/demultiplexer has been reduced through the modification of the torch for flame hydrolysis deposition (FHD) process. The conventional type FHD torch was changed into a precursor-premixed type torch, which enhanced the AWG crosstalk level by 5-8 dB. The results were also compared with the characteristics of AWGs of which the core layers were fabricated by the plasma-enhanced chemical vapor deposition process.
