Four models of lateral current spreading in double-heterostructure stripe-geometry lasers

Four models of current spreading in double-heterostructure stripe-geometry lasers, both with and without a zinc diffused cap, are presented and compared. These models range in complexity from a simple analytic model to a more complex consistent model. Results show that each of the four models predic...

Zusammenfassung:	Four models of current spreading in double-heterostructure stripe-geometry lasers, both with and without a zinc diffused cap, are presented and compared. These models range in complexity from a simple analytic model to a more complex consistent model. Results show that each of the four models predicts essentially the same current spreading and carrier diffusion in the active layer.< >
