摘要： The period-one oscillation produced by an external optical pulse injection driven semiconductor laser is applied to clock recovery and frequency division. By adjusting the repetition rate or injection power of the external injection optical pulses to lock the different harmonic frequencies of the period-one state, the clock recovery and the frequency division (the second and third frequency divisions) are achieved experimentally. In addition, in frequency locking ranges of 2GHz and 1.9GHz, the second and third frequency divisions are obtained with the phase noise lower than --100dBc/Hz, respectively. Our experimental results are consistent well with the numerical simulations.
