摘要：
The transmission peak wavelength of a fibre-pigtailed arrayed-waveguide silica-on-silicon grating (AWG) demultiplexer has been shifted using a 248nm excimer laser without penalties in crosstalk or insertion loss. The transmission peak shift and shape were monitored while trimming. A wavelength shift of 0.77nm (94GHz) was achieved while keeping a crosstalk of -25dB for 400GHz channel spacing and an insertion loss < 7dB.
