摘要：

In this work we report a NOLM configuration based on a Semiconductor Optical Amplifier (SOA) and a highly nonlinear Microstructured Optical Fiber (MOF) that offers a stable compression ratio and reshaping capabilities for pulses obtained from Gain Switching diode laser sources. The device is perfectly adapted to the particularities of such sources, namely their low power, their asymmetric nature and the presence of wide pedestals, without the need of intermediate stages to pre-process these optical pulses. Experimental and numerical studies are presented where the influence and importance of the dynamic of the Semiconductor Amplifier on the overall pulse compression performance of the NOLM is explored. Results show that the saturation and gain compression are important to understand the system behavior. Along with these effects, the influence of the alpha factor and its dependence on the carrier density under high input conditions is evaluated. Numerical and experimental results show relevant agreement, what sheds light on the device behavior and helps understand the influence of the several physical effects behind it.
