摘要:

Undesirable nonlinear ’’kinks’’ in light‐output–vs–current characteristics of stripe geometry double‐heterostructure (DH) injection lasers are significantly reduced by stabilizing the transverse modes along the junction plane. Built‐in passive guiding mechanism is introduced by growing planar (AlGa)As/GaAs DH layers on a grooved GaAs substrate.
