2.1 Sources and source noise
Like any electromagnetic oscillator, a laser never delivers a perfect sine wave. This is affected by amplitude and phase noise, which can degrade the performance of communication systems . Amplitude fluctuations are usually characterized by Relative Intensity Noise (RIN), defined as the ratio of the power spectral density of normalized power fluctuations to the average transmitted power. If the...
