Abstract

Data are presented on a high-performance native-oxide coupled-stripe AlyGa1-yAs-GaAs-InxGa1-xAs quantum well heterostructure laser realized by the recently introduced simple process of "wet" oxidation (H2O vapor+N2, ≳400°C, 3 h) of the upper AlyGa1-yAs confining layer. If the native oxide between active stripes (ten 5 μm stripes on 10 μm centers) is brought into closer proximity with the waveguide and quantum well region (i.e., from 0.53 to 0.4 μm), the 10-stripe laser operates decoupled because of increased (coupling) absorption losses and some index guiding.
