Notes:
Broad-area lasers are fabricated with a long (80–100 μm), nonabsorbing window at each end. The window is shown to dramatically improve the spatial mode properties, stabilizing and smoothing the near field, and reducing the far field from 5°–15° to as low as 2°. This improvement comes at the expense of an increase in threshold current and reduction of quantum efficiency.
