    摘要: The present invention relates to a multi-layer dopant barrier and its method of fabrication for use in semiconductor structures. In an illustrative embodiment, the multi-layer dopant barrier is disposed between a first doped layer and a second doped layer. The multi-layer dopant barrier further includes a first dopant blocking layer adjacent the first doped layer and a second dopant blocking layer adjacent the second doped layer. A technique for fabricating the multi layer dopant barrier is disclosed. A first dopant blocking layer is formed at a first temperature, and a second dopant blocking layer is formed at a second temperature over the first barrier layer.

    摘要: An integrated monolithic laser-modulator component having a multiple quantum well structure. This component includes an InP substrate, a laser (L) formed from a stack of semiconductor layers epitaxied on the substrate, including an active and absorbent layer and a periodic Bragg grating fixing the emission wavelength of the laser to a value slightly above an optimum wavelength of the laser gain peak. An electrooptical modulator (M) is formed from the same stack of semiconductor layers, with the exception of the Bragg grating, the active layer of the laser and the absorbing layer of the modulator being formed by the same epitaxied structure having several constrained or unconstrained quantum wells, the modulator functioning according to a confined Stark effect. The semiconductor layers of the laser and those of the modulator are electrically controlled.
