Abstract

A novel all-optical frequency multiplication/recovery technique based on a repetitive pulse intensity matching is proposed and demonstrated. Unlike a rational harmonic mode locking requiring additional stabilizing functions, this technique can be used to generate stable and input polarization independent optical pulse trains with the repetition rates of 2.5–12.5 GHz from 2.5 GHz driving pulse. Also, this scheme can be applied to the extraction of the clock signal from a pseudorandom bit sequence signal.
