Theoretical analysis of single‐mode AlGaAs‐GaAs double heterostructure lasers with channel‐guide structure

This study is concerned with electromagnetic wave propagation in AlGaAs‐GaAs double heterojunction lasers with a channel‐guide structure. An analytical solution to Maxwell’s equations in a structure of sufficient complexity to describe a channel‐guide five‐layer laser is presented. Numerical calculations based on the solutions were made for a specific set of parameters obtained from a channel‐guide laser grown by metal‐organic chemical vapor deposition (MO‐CVD) in our laboratory. Some analytical predictions for a fundamental mode oscillation are also included.
