Abstract: | 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. |
