Fabry–Pérot Laser Characterization Based on the Amplified Spontaneous Emission Spectrum and the Fourier Series Expansion Method

摘要

Comprehensive Fabry–Pérot laser characterization based on measurements of the amplified spontaneous emission spectrum analyzed using the Fourier series expansion method is presented. The parameters of net modal gain, internal loss, quasi-Fermi level separation, linewidth enhancement factor, injection efficiency, and geometric spontaneous emission factor can all be extracted.
