Abstract
A portion of the surface of the first structure is protected by an oxide deposit, and the non-protective layers are etched down to a stop layer. The layers in the etched zone are then built up by molecular beam epitaxy, and one of the built-up layers is given a composition that is different from the composition of the corresponding adjacent layer in the first structure. The method is applicable to fabricating an integrated semiconductor comprising both a laser and a modulator.
