Analysis of Direct Detection Lightwave Systems with Optical Amplifiers.

摘要

We provide a detailed analysis of direct detection lightwave systems employing an optical preamplifier at the receiver and derive the closed form expression for the bit error probability of WDM systems employing on-off keying (OOK) as modulation format. In our analysis, we consider various cases in which the receiver model uses either a finite-time integrator or Fabry-Perot filter operating in a single channel or multi-channel environment. We take into account the optical amplifier noise, the postdetection receiver noise, the shot noise, and the effect of the nonzero laser linewidth. FSR, responsivity, ACI, ISI.
