Abstract

Analog AM photonic links are used in many applications such as cable TV and microwave links in phased arrays. The major issues of these links are linear dynamic range and rf efficiency. We will show in this paper that, while the rf efficiency is always increased by the optical amplifiers, the linear dynamic range may be significantly reduced. The effect of the optical amplifier on the signal to noise ration can always be expressed as a laser source with an equivalent RIN noise. The signal to noise ratio is affected less when the amplifier is placed closer to the source.
