Two Dimensional Analysis of the GaAs Double Hetero Stripe-Geometry Laser

Abstract

The GaAlAs/GaAs stripe-geometry laser is analyzed using a new technique called the effective dielectric constant (EDC) method. Unlike previously reported techniques, use of the EDC method allows both vertical and sideward directions in the cross section of the laser to be taken into account in analyzing the field confinement mechanism. Computed data on field concentration and cutoff behavior are presented.
