One more thing that I like particularly on WDM-Phasar is that it offers possibility of “AWG Design vizard”, that is, it designes the AWG structure itself, so the user does not have to do any calculations. Very usefull particularly for the beginners.
However, disadvantage of the tool is the speed. It is much slower that the other photonic tools. For example 128-ch, 10 GHz AWG took about 2 months.
Nevermind, the tool (compared to other photonics tools) produces “real” simulated results matching with the measurements. That’s the most important.
