Problems, proposed solutions, and recent results related to the development of solid-state oscillators, detectors, mixers, diode multipliers, and antennas at THz frequencies are addressed. Individual topics considered include: submillimeter heterodyne remote sensing of upper atmospheric gases, planar dipole array antenna with an elliptical lens, twin slot antenna structures integrated with microbolometer detectors for 94-GHz imaging. Also discussed are: quantum-well and quantum-barrier diodes for generating submillimeter wave power, planar Schottky barrier mixer diodes for space applications at submillimeter wavelengths, GaAs Schottky barrier varactor diodes for submillimeter wavelength power generation, planar doped barrier devices for subharmonic mixers.
Where two frontiers meet
Current research projects conducted at the JPL Center for Space Microelectronics Technology are briefly reviewed. These include the development of a new miniature tunneling Goday cell that can be made into arrays. This tunneling IR detector is sensitive to radiation through the infrared and is particularly suited to room temperature measurements of the mid to far infrared. Other developments include ballistic-electron-emission microscopy, a next-generation spacecraft on-board computer using the Direct Memory Access Co-Processor, a 1-sq cm custom chip with 40,000 transistors, new neural network chips, the third-generation hypercube, and a new Hyperswitch Adaptive Message routing VLSI chip.
