The semiconductor optical amplifier (SOA) is a technology that may be crucial in future optical networks, as a low-cost in-line amplifier or as a functional element. As fiber networks extend closer to the end user, economical ways of improving the reach of these networks are important. SOAs are small, relatively inexpensive and can be readily integrated into photonic circuits. Problems persist with the development of SOA, however, in the form of a relatively high noise figure and low saturation power, which limits their use in many circumstances. The aim of this work to outline a concept to increase the saturation output power so that the SOA can achieve the performance required. Also, to improve the applicability of SOA in a switched environment, there must be a provision for varying the clamped gain. For this, distributed feedback grating or distributed Bragg reflector are integrated into the SOA for inducing lasing oscillation. It is well known as gain-clamped SOA (GC-SOA), in which the induced lasing oscillation clamps the gain and suppresses the gain saturation. It has already been studied the methodology for adjustable gain clamping which will give us an insight into how the clamped gain can be varied instead of being fixed. In the present work, a model is constructed which has been designed with unbalanced grating configurations combined with non-uniform current injection.
