An overview of various high-frequency InP HBT oscillators that can be used as terahertz signal sources is presented. A 300-GHz fundamental-mode oscillator was first developed based on InP HBT technology, and then subsequently modified for additional oscillators with improved function or performance, which includes a 300-GHz voltage-controlled oscillator (VCO), a 280-GHz high-power oscillator with 10-dBm output, and a 600-GHz push-push oscillator. The 300-GHz oscillator was also successfully employed as a signal source for THz imaging, which is also briefly described.
