Correlation coefficient measurement of the mode-locked laser tones using four-wave mixing

Appl Opt. 2016 Jun 1;55(16):4441-5. doi: 10.1364/AO.55.004441.

Abstract

We use four-wave mixing to measure the correlation coefficient of comb tones in a quantum-dash mode-locked laser under passive and active locked regimes. We study the uncertainty in the measurement of the correlation coefficient of the proposed method.
