Abstract

Photorefractive optical amplification, while useful, is a slow process. Under some circumstances, however, it amplifies optical signals effectively even when one is modulated at a relatively high frequency. We determine the reasons for this capability (what we have called the "Fast Photorefractive Effect") and analyze its enhanced bandwidth, improvements over standard photorefractivity, and limitations.
