摘要：
We present a detailed investigation of the intensity noise dependence on the injection current of semiconductor lasers under moderate feedback. With increased injection current low- and high-frequency intensity fluctuations shift towards higher frequencies. A comparison between the experimental results and a small-signal analysis of the laser rate equations shows that both types of frequency fluctuations can be interpreted as complex relaxation oscillations of a laser diode with external feedback. The simple model describes reasonably well the frequency shift and the spectral width of the fluctuations observed. © 1990 IEEE
