Semiconductor Optical Amplifier Studies Under Optical Injection at the Transparency Wavelength in Copropagative Configuration

Résumé

We experimentally and theoretically demonstrate the SOA gain recovery time dependency on the probe signal wavelength and power, when injecting a continuous wave (CW) high power assist light in the device. In our study, pump, probe and assist light waves are all co-propagative. Experimental and numerical results show that the gain recovery time is significantly reduced over a wideband of probe wavelengths, due to the assist light use. The reduction is more pronounced for low probe powers. A theoretical evaluation of the transparency wavelength dependency on both the probe wavelength and power is presented. Then, a study on assist light power effects on the SOA dynamics as well as pump and probe wavelengths effects on SOA gain recovery time is performed.
