Abstract : The program we have completed will be discussed in three basic sections. The first will deal with the important developments in optically controlled generation of millimeter waves. This work started from earlier results of mixing high frequencies internally using FETs and HEMTs. In this study, these initial experiments were successfully extended to radiating systems in free space to using new HBTs and semiconductor laser. Section (B) will deal with our advanced picosecond measurements and HEMTs, HBTs and Hot Electron Transistors. It will also present our measurement of bandwidths of channel guides on wafer using our mixing and picosecond techniques. Finally, in section (C), we discuss the new Quantum Well Impatt, polymer modulators, optical guide developments and InSb devices. Many of these new concepts are just becoming experiment. The. overall view of integration is discussed in this third section.
