Comment on Optical Frequency Combs

Comments

Nice to see some more posts about light communications on HN. I have had the pleasure talking with people who developed this tech & see it in action.

Apparently, it is a big step towards purely optical network switching.

Once optical comb sources become economically available off the shelf, they should be game-changers in several fields from spectroscopy to time/frequency work. Right now everything you can buy is still around 6 figures AFAIK.
