Parametric Amplification: Anomalous and Normal Dispersion Behavior

This lecture delves into the concepts of parametric amplification, focusing on anomalous and normal dispersion behavior. The instructor explains the amplification in phase-matched anomalous regime and normal dispersion based on negative beta 4, as well as expresses the bandwidth of single pump amplifiers. Through the slides, the lecture covers topics such as non-phase-matched behavior, phase-matched behavior, single pump peak of the parametric gain, typical gain curves in anomalous and normal dispersion, broadband and narrowband gain, gain bandwidth, and the effect of dispersion fluctuations. The lecture concludes with a quiz on parametric gain measurements with different waveguide lengths and pump powers.
