Abstract:
1. An integrated optoelectronic device fabricating method of fabricating an integrated optoelectronic device provided with a plurality of waveguide-type optoelectronic elements formed on an InP substrate and connected in an end-to-end fashion by butt jointing, said method executing at least one cycle including the steps of: forming a first optical waveguide element on an InP substrate forming a mask pattern on the first optical waveguide element formed on the InP substrate; removing part of the first optical waveguide element not covered with the mask pattern by etching to expose a part of a surface of the InP substrate; and growing crystal layers to forming a second optical waveguide element containing InGaAlAs on the exposed part of the InP substrate; wherein an InGaAsP layer is formed on an exposed part of the surface of the InP substrate at a crystal growth temperature lower than a crystal growth temperature for growing layers to form the second optical waveguide element.
