“…The oscillations of both magnitudes are correlated for negative values of the detuning. These oscillations of the timing jitter have been also found in the repetitive gain-switching of single-mode semiconductor lasers subject to optical injection (Dellunde et al 1997). Similar oscillations are obtained when reference values between P on /4 and P on /2 are considered.…”

“…The mean spectrum width [12] is 14.8 GHz for the free-running VCSEL and 9.3 GHz for the VCSEL subject to optical injection with a frequency detuning Δν= 5 GHz. Therefore a reduction of 37% in the spectrum width is obtained by optical injection.…”

We report an experimental and theoretical investigation of the effect of optical injection on the characteristics of optical pulses generated by gain-switching a 1550 nm single transverse mode vertical-cavity surface-emitting laser (VCSEL). Under continuous wave operation the VCSEL emits in a linear polarization along the whole current range. The experimental analysis of the effect of external optical injection on the timing jitter, maximum power, and pulse width of optical pulses generated by gain-switching the single mode VCSEL is performed for several repetition rates and for different values of the detuning between the frequency of the optical injection and the VCSEL. Experimental results show that for 1 GHz repetition frequency, jitter reductions greater than 70 % can be obtained over a 47 GHz frequency detuning range with a slight increase of 22% in pulse width with respect to the solitary case. A clear anticorrelation between the maximum power and pulse width is also obtained. A theoretical study is also performed by using a model that incorporates both spatial dependence of carrier density and optical field profiles. The two polarization modes are also taken into account in the model. The theoretical results are in good agreement with the experimental results.

“…When the single-mode continuous-wave (cw) output from a master laser is injected into the cavity of a gainswitched FP slave laser, the multimode field rate equations for the amplitude and the phase of the optical field and the carrier number in the active region of the slave laser are 10,11…”

An external injection-seeding scheme with selected wavelength feedback to the master Fabry-Perot laser diode is developed to improve the side-mode suppression ratio (SMSR) and extend the wavelength tuning range of the injection-seeded optical short pulses. A SMSR of higher than 31 dB over a wavelength tuning range of 20.4 nm has been obtained. For a SMSR of higher than 40 dB, the wavelength tuning range achieved is 13.8 nm. The system is simple and can operate at arbitrary repetition frequency.
