Abstract

The time response of the Raman effect is associated with the vibrations of the molecules in the gain medium and is on the order of several hundred femoseconds [1]. Compared to current data rates, this energy transfer is practically instantaneous resulting in very fast-gain dynamics. Fast-gain dynamics in semiconductor amplifiers results in a large amount of crosstalk between signal channels, even at high frequencies, and poor system performance. However, the Raman effect in optical fibers is quite weak such that the gain cavity needs to be several kilometers long.
