Abstract:
A method for the manufacture of a buried structure device and for the integration of this device with an optical guide in a photonic circuit, the method comprising:(A) growing, on a buffer layer doped with carriers of a first type, itself deposited on an entire surface of a substrate doped with carriers of the same type, a guiding layer formed by a non-doped quaternary compound, then(B) growing an extremely thin intermediate layer highly doped with carriers of the first type, then(C) growing an active layer formed by a non-doped quaternary compound, then(D) growing a protection layer doped with carriers of a second type, then(E) etching the active layer in the form of at least one strip and leaving the intermediate layer, the guiding layer, and the buffer layer substantially unetched, and then(F) growing a sheathing layer doped with carriers of the second type, the sheathing layer burying the at least one strip of the active layer.
