Paper Abstract

We present the influence of an assist light beam injection at the gain transparency wavelength inside Semiconductor Optical Amplifiers (SOAs), which is proposed as a useful method to enhance the SOAs static and dynamic characteristics. Experimental static measurements demonstrate 4.6 dB improvement in saturation output power of SOA measured at -3 dB while maintaining a high level gain. A shorter gain recovery time is obtained which is essential for all-optical high bit-rate applications. Moreover, photodetection dynamic response shows an enlargement in the SOA photodetection bandwidth which implies a carrier lifetime reduction.
