Using numerical simulation, the search for designs of asymmetric barrier layers (ABLs) in a laser
diode with a GaAs waveguide emitting at a wavelength of λ = 980 nm is carried out. A pair of ABLs adjoining
the active region on both sides blocks undesired charge-carrier flows and suppresses parasitic spontaneous
recombination in the waveguide layers. Optimal designs ...
