This lesson shows the performance of the Average power model in analysis of the 100 nm bandwidth Raman amplifier with multiwavelength backward pump. The parameters considered are close to these used in the experiment of [1]. The same experimental situation has been...

In this lesson, we will use the gain flattening type of optimization to optimize the pump powers for flattening the gain of a Raman amplifier. Fiber Raman amplifiers are recently getting much more attention in WDM systems due to their greatly extended bandwidth and...

In this example, we show that the Gain Flattening type of optimization can be used to design multi-wavelength pumped Raman amplifiers with a flattened gain. Given amplifier specifications such as signal level, required gain profile, and number of allowed pump...

This lesson demonstrates generating the transients based on add-drops in signals in a Raman amplifier. In this example, we simulate a counter-pumped Raman amplifier for a small number of signals. Then the results are compared with the ones found in the literature. The...

Amplification of ultra-short optical pulses in SOA produces considerable spectral broadening and distortion due to the non-linear phenomenon of self-phase modulation. The physical mechanism behind SPM is gain saturation, which leads to intensity-dependent changes of...
