The Effect of the Input Energy on the SOA Gain With Non-Uniform Biasing
Source: Universiti Teknologi Malaysia
This paper investigates the effect of input optical pulse energy on the total gain of the Semiconductor Optical Amplifier (SOA) injected with a non-uniform bias current. For ultra-high data rate applications it is essential that the SOA has a fast gain recovery response, thus resulting in maximum SOA gain and reduced gain standard deviation. SOA with higher gain standard deviation will reduce the overall gain of the output optical pulses. Therefore in this paper, non-uniform biasing techniques are adopted in order to accelerate the gain recovery while minimizing the gain standard deviation for high-speed optical applications. The theoretical SOA operation principle is demonstrated using segmentized model with the complete rate and propagation equations.
