Abstract
Spectral linewidth measurements of 1.55 μm InGaAlAs/InP vertical-cavity surface-emitting lasers (VCSELs) employing a buried tunnel junction are reported. A narrow linewidth around 28 MHz was obtained at a power level of 0.5 mW using the self-heterodyne method, and an estimation for the linewidth enhancement factor is given.
