Abstract

In this paper, firstly we established the theoretical model of the relationship between correlation and wavelet vanishing moment of 1/f noise. Then we designed and built the 1/f noise measurement system for semiconductor laser diodes (LDs). Based on this, we introduced the measurement method of low-frequency electrical noise in semiconductor LDs and the extraction process of parameters associated. The wavelet transform decorrelation calculation is applied to the time-domain of the low-frequency noise signals, and the calculation and analysis of the relation between wavelet coefficients variances and scales are completed. The experimental results show that the noise wavelet coefficient correlation E and the vanishing moment N of wavelet function satisfy the decorrelation theoretical model at some scales, which implies that the low-frequency noise signals measured from the LDs belong to 1/f noise. Besides, the wavelet coefficient variance calculation results indicate that the noise measured in the experiments is 1/f noise from another aspect. Finally we theoretically proposed a new idea of semiconductor laser 1/f noise judging based on the methods above.
