Paper Abstract

We realized different types of optoelectronic integrated circuits by integrating on the same silicon chip: photo detectors, linear or logic electronic circuits, waveguides, coupling elements. This paper present the design, modeling and experimental realization of these components, underlining the original approaches and results. Special structures of photo detectors were designed, in order to allow optical coupling with waveguides and monolithic integration with electronic and photonic circuits. Original models for these photo detectors were developed. The electronic circuits we realized, unlike those reported in literature, can operate at very low input currents. Also new materials and processes were studied and experimented in order to improve the component performance. Specific technologies for optoelectronic circuits, compatible with either CMOS or bipolar processes, were established by analyzing the relationships between the technological parameters and circuit characteristics. Also the matching with waveguides and micro mechanical structures technologies was analyzed and experimented, as the aim of our research activity was to realize different types of micro-electro- mechanical systems for sensor applications.
