“…Besides, the SOA smallsignal gain can be maintained when the HB is close to the transparency wavelength [25], [27] . We have demonstrated that this technique improves the SOA transmission performance as well [28]- [29]. A detailed knowledge of the gain transparency evolution is necessary to obtain optimized performances when the HB injection technique is employed in SOAs.…”

We investigate by numerical calculations the evolution of the gain transparency wavelength λ tr of a semiconductor optical amplifier (SOA) over a wide range of the optical signal power, wavelength, and the SOA bias current. We show that the most critical parameter to control is the input signal power. Our results demonstrated that for a low input signal power, λ tr is the same for all the signal wavelengths. A trade-off over a 30 nm range of HB wavelength in function of the injected signal parameters (wavelength, power and gain) is necessary to an optimized improvement of the SOA performance by the holding beam (HB) injection.
