Abstract
A novel method for estimating the linewidth enhancement factor a of semiconductor lasers is developed. The correlation between AM and FM noises of a CSP-type AlGaAs laser was measured in the frequency range above 1 MHz. From the measured correlation, the linewidth enhancement factor α is estimated to be approximately −2.2 to −2.8.Keywords
