Abstract :
We have described a novel holographic technique which is capable of achieving a variety of WDM functions by using a phase-modulation active arrayed waveguide grating (AWG). Simulations have demonstrated EDFA equalisation of 12dB for 8x 100 GHz spaced WDM channels, with inter-channel ASE suppressed by greater than 20 dB. The holographic designs are robust to individual phase-modulator failures and fabrication phase errors.
