Pulse shapes reconfigured on a pulse-to-pulse time scale by using an array of injection-locked VCSELs

We demonstrate line-by-line pulse shaping of optical comb lines separated by 6: 25 GHz. An array of injection-locked VCSELs independently modulate four optical comb lines at frequencies up to 3: 125 GHz, updating the pulse shape on the time scale of the pulse period.
