ABSTRACT

The theory presented indicates that when the active region of a semiconductor laser is very thin the linewidth enhancement factor differs significantly from Henry’s 1 + α2 factor and can be reduced by a factor of 4. Petermann’s K-factor may also play a role in the plane perpendicular to the junction.
