Abstract
A normalized threshold current density Jth/d = 4.0 kA cm−2 μm−1 has been determined for pulsed broad‐area room‐temperature GaAs1−x′Sbx′/AlyGa1−yAs1−xSb x DH lasers of length 380 μm over a range of active‐layer thicknesses d. Thresholds as low as 1.2 kA cm−2 and differential efficiencies up to 35% have been obtained in the wavelength range 0.99–1.06 μm. cw operation of stripe‐geometry lasers is also described.This publication has 9 references indexed in Scilit:
