1  Introduction

2  Classical Laser Noise Model
    2.1 Semi-Classical Approach (Maxwell equation)
    2.2 SDEs: the Langevin Equations (After Linearization)
    2.3 Characteristic of the Model (RIN, pdf, Linewidth…)

It’s Basically the summary of Yariv’s paper.

3  Generalization of the Model
    3.1 ARMA (spectrum)
    3.2 Levy Noise Process (distribution)
    3.3 Levy Driven ARMA
    3.4 Characteristic of the Generalized Models (Show how the generalized model is capable of capturing the features of the laser noise. Highlight)

The hightlight of the first part of the paper.

4  Estimation of the Parameters
    4.1 ARMA
    4.2 Levy Noise (hard to do in the general case; use parametric families instead)
    4.3 Simulation and Qualitative Analysis

Interperting the result of the simulation. Attach physical meaning to the model.

5  Coherent Optical Communication System (focus on QPSK, exclude all but laser noise)
    5.1 Introduction
    5.2 Laser Noise in QPSK (classical noise model)
    5.3 Levy-Driven ARMA Laser Noise Model in QPSK (analysis and simulation)

Try to formulation the problem as an estimation problem and see if it’s possilbe to derive some bounds.

6  Conclusions
