Illustration of current path in bipolar-cascade lasers.
Schematics of shallow (Sample A) and deeply etched (Sample B) pillars, illustrating diffraction loss from the bottom DBR for Sample A.
Light-current-voltage plot of Samples A and B under pulsed operation at .
Differential quantum efficiency vs pillar diameter for Sample A (square) and Sample B (circle).
Simulated diffraction loss for an pillar vs number of DBR periods, with the top axis indicating the corresponding reflectivity. The number of active stages required to maintain constant threshold gains of (circles), (squares), and (diamonds) is also plotted as a function of the number of DBR periods and reflectivity.
