Abstract
An optoelectronic device and method of making the same. The device comprising: a substrate; a regrown cladding layer, on top of the substrate; and an optically active region, above the regrown cladding layer; wherein the regrown cladding layer has a refractive index which is less than a refractive index of the optically active region, such that an optical mode of the optoelectronic device is confined to the optically active region.
