Abstract
The waveguide mechanism in channeled-substrate-planar (CSP) structure (AlGa)As lasers is analyzed. The light leakage into the GaAs substrate outside the channel is shown to provide effective refractive index and loss differences, which function to stabilize the transverse mode in the junction plane. Observed light output vs current characteristics and mode patterns in the lasers justify the theoretical model.Keywords
