Nice. Now if only they would mass produce them and sell them for production cost + 20% or at least something remotely reasonable.  :)

From the optica paper:

Quote

Experimentally, this consists of a semiconductor laser local oscillator locked to the rubidium-87 two-photon transition at 385.284 THz that is coherently divided down to a 22 GHz clock tone by stabilizing a pair of interlocked microcombs to the local oscillator.

That's 26 octaves above middle E!

I fee like if this clock is low power it will be some kind of game changer.
