A novel optical frequency shifter based on an appropriately driven electro-optic modulator will be presented. It is universally applicable to optical frequency combs corresponding to periodic trains of pulses. The method comprises well-directed optical carrier phase shifting between subsequent pulses without intrusion into or modification of the comb generator. It offers both wide optical bandwidth (many THz) and agile tuneability (10 THz/s), allowing the lines to be continuously swept from one comb end to the other, following a target temporal frequency evolution.
