If we are able to provide 1Tbps at a single port in a single data stream, then for sure we will have the memory.
Of course. And, it's doable even with packet buffers with realistic size and packet loss possibility. Otherwise, parallel datapath requires so much money and power that those for routing table is negligible from the beginning.
Today we use DWDM,
That's fine. The point is to switch all the wave lengths at once, just like EDFAs amplify all the wave lengths at once.
Or, can you make already pipelined memory operating at 200MHz 5 or 50 times more faster by 5 or 50 times more stages of pipeline?

solves your "problem" which isn't one.
It's merely 1.25 times faster than my example that it is no solution.
The problem is just a "I DO NOT WANT THIS", "I BELIEVE", "I DON'T LIKE" by certain people.
The problem is merely that you don't know the capability of combined photonic/electric circuit. Masataka Ohta
