Abstract It is shown theoretically that a GaAs/AlGaAs laser diode design using an asymmetric waveguide structure and a bulk active layer (AL), located close to the p‐cladding, can provide high output power in a single, broad transverse mode for sho

Threshold properties and pulsed output of AlGaInP visible-emitting lasers with an asymmetric waveguide structure and a bulk active layer are analysed. The effects of the current leakage, increased by the heating of the laser due to the proximity of t

A semiconductor laser design for efficient, high power, high brightness red light emission is proposed, using a large optical cavity asymmetric waveguide and a bulk active layer (AL) positioned very close to the p-cladding. The low threshold carrier

An effective one-dimensional travelling wave model is used to analyse the performance of a short-cavity asymmetric-waveguide high pulsed power laser diodes. The effect of longitudinal inhomogeneity is proven to be modest for practical laser designs.
