Millimeter-Wave Applications of Semiconductor Dielectric Waveguides with Plasma Layers (Surface or Buried) Generated from Semiconductor Lasers.

摘要

This research program was aimed at the theoretical and experimental investigations of semiconductor devices and waveguides with applications in millimeter wave systems. The major components considered included waveguide phase shifters, attenuators, and periodic structures designed to operate at the Second Bragg frequency. Most of the effort was directed at theoretical and experimental understanding of the second-order Bragg structures since these components produce the most efficient radiating antennas. With a goal of locking several independent oscillators through gratings in the dielectric waveguide, the grating plays one of the most important roles in the system integration. Accordingly, we developed two comprehensive computer models of dielectric gratings and made experimental measurements on more than fifty waveguide structures.
