High Frequency Optoelectronic Integrated Systems

摘要

In this high frequency optoelectronic program we have investigated thedevelopment of optical components and elements for integration of light into microwave and millimeterwave systems. This involved the development of new types of modulators, detectors and on wafer optical guides. particular attention was paid to the requirements of integration and epitaxial liftoff was investigated as a means of incorporating different materials technologies. In combination with our polyimide optical guides, active polymer modulators, and microwave elements, this lift off technology has permitted the development of new unique systems. Both HEMT and HBT phototransistors were developed and tested in this effort using picosecond techniques and optical mixing. A unique traveling wave HBT, side coupled phototransistor has been designed and fabricated.
