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.

摘要

分析了沟道衬底平面（CSP）结构（AlGa）As激光器中的波导机制。结果表明，进入沟道外GaAs衬底的光泄漏提供了有效的折射率和损耗差异，其作用是稳定结平面中的横向模式。激光器中观察到的光输出与电流特性以及模式图案证明了该理论模型的合理性。
