FIG. 1.

Calculated conduction and heavy hole band edges through the center of a DWELL. The lines with circles at the end show the calculated electron and heavy hole ground state energies, and the highest light-holelike valence state. The left inset shows a schematic diagram of the dash with the dash long axis along (1-10) and the short axis along (110). The right inset shows the axes of polarization.

FIG. 2.

(a) Calculated TE(110)- (black solid), TE(1-10)- (red dashed dotted), and TM-polarized (blue dashed) absorption spectra and (b) ratio squared transition matrix elements.

Image of FIG. 3.
FIG. 3.

(a) TE(1-10) (red dashed-dotted) and TM (blue dashed) photovoltage spectra for DWELL laser sample. (b) Measured ratio of TE(1-10) (red dashed-dotted) to TE(110) (black solid) SE spectra. (Inset) Polarized SE spectra.

Image of FIG. 4.
FIG. 4.

Left axis: plot of total threshold current (filled black diamonds) and total radiative contribution to threshold (filled red triangles) as a function of temperature. Right axis: Normalized external differential quantum efficiency (open blue circles) for a DWELL laser.
