Abstract
Monolithically integrated devices are disclosed in which a laser having a capping layer with a relatively high conductivity imparting ion concentration is laterally offset along a planar surface from a surface layer having a lower conductivity imparting ion concentration. The monolithically integrated laser and surface layer are formed by providing laterally offset channels in a planar substrate surface and selectively epitaxially growing the required laser layers and the surface layer in separate channels.
