Abstract :
A "rib-guide" optical-waveguide structure proposed as a means of injection-laser transverse-mode control, independent of current distribution, has been demonstrated in an AlGaAs double-hereto-structure (DH) diode laser. The new structure showed stable single-transverse-mode operation at currents to twice threshold with small rib dimensions, and the observed higher order modes in large structures are in reasonable agreement with theory.
