摘要:
The cavity length dependence of the threshold current for separate confinement quantum well lasers with a single well, three wells, and six wells is studied. Only the single quantum well laser showed the anomalous increase of threshold current at short cavity length. Comparison of the experimental results with theoretical calculations concludes that the polarization enhancement of the oscillator strength in a quantum well has to be taken into account in the gain spectrum calculation of the quantum well laser.
