Intensity cross-correlation functions of the longitudinal modes of Fabry-Perot 1.3 mu m InGaAsP lasers

Experimental measurement of intensity cross-correlation functions and autocorrelation functions of the longitudinal nodes of multimode 1.3- mu m InGaAsP lasers are discussed. It was found that cross-correlation functions have much more structure than anticipated. As the time delay is increased, the mode interaction can change from correlation to anticorrelation and vice versa. This observation should have a bearing on mode-partition interactions.<
