Abstract

The geometric spontaneous emission factor is calculated from the amplified spontaneous emission spectrum of a Fabry-Pérot (FP) laser diode. The optical loss and quasi-Fermi level separation are determined first using the Fourier transform method with the influence from the instrument response function being taken into account. From this the geometric spontaneous emission factor is calculated to be 5.95×10^-3 just below laser threshold.
