Abstract
Diode lasers with active and/or cladding regions whose thicknesses vary spatially parallel to the p‐n junction are analyzed. It is shown that lateral real‐refractive‐index waveguiding occurs and that a diffusion gradient exists which propels the injected charges into the lasing modal volume. Lateral mode patterns and thresholds are calculated and sensitivity to higher‐order lateral mode oscillation is evaluated for various stripe widths and spreading resistances. Results are shown to agree well with experimental data.Keywords
