> Why is the headline misleading? for reference, the headline is currently "Record-breaking chip can transmit entire internet's traffic per second."

The "chip" is a CW laser, so it transmits no data.

It's a little hard to tell from the article + PR, but I think the result is a laser with a stabilized frequency-comb output suitable for WDM that has been implemented on a single die (which is still a nice result.)

Perhaps I missed that they implemented an entire transmitter chain on the "chip", but I believe the chip innovation is the continuous photon source, not the data transmission.
