Abstract :
We proposed a method to estimate the laser phase noise using the phase noise to intensity noise conversion based on the direct detection (DD) technique. It is shown by simulation that the estimated results approach when the laser line-width is no larger than 1MHz. Besides, compared with coherent detection -based phase noise estimation, the DD technique provides cost-efficient solutions.
