Abstract :
In this letter, the fabrication tolerance of conventional and multimode interference (MMI)-flattened arrayed waveguide gratings (AWGs) is compared. It is shown that the crosstalk of an MMI-flattened AWG is approximately equal to that of a conventional AWG with the same 3-dB bandwidth. However, the dispersion of the MMI-flattened AWG is greater than that of the conventional one and this poses limitations in the maximum bit rate in a cascade of MMI-flattened AWGs.
