ABSTRACT:
In an optoelectronic device, light is restrained from propagating in one or both confining layers on either side of an active layer by forming one or more photonabsorbing barriers in one, or both, confining layers. A photon absorbing barrier can be formed by proton bombardment of a confining layer, by producing a protrusion from the substrate into the adjacent confining layer, or by producing a protrusion from a capping layer into the other confining layer, or by combinations of these. Spaced apart barriers can define a device, or sections of a multi-sectioned device, for example a monolithic light emitting diode and modulator.
