Abstract
We calculate the relaxation oscillation corner frequency fr and the linewidth enhancement factor α for both a quantum well and a quantum wire semiconductor laser. A comparison of the results to those of a conventional double heterostructure device indicates that fr can be enhanced by 2× in the quantum well case and 3× in the quantum wire case while α is reduced in both cases.Keywords
