Optimization of Raman Fiber Amplifiers

Optimization of Raman Fiber Amplifiers

The utilization of high-gain bandwidth in Fiber Raman Amplifiers (FRA) requires multiple pumps as well as a careful adjustment of their wavelengths and powers. Due to the large number of variable parameters, this is only feasible with the help of special optimization algorithms. The pumps strongly interact in the fiber. [pdf]

Transimpedance Amplifier T-type Amplification

Transimpedance Amplifier T-type Amplification

This transimpedance amplifier with a T-network feedback configuration converts an input current into an output voltage. It's also a common building block that helps explain the performance and stability limits of many other op-amp circuits. [pdf]
