چکیده
The millimeter-wave and THz frequency (f > 100 GHz) range remains one of the most underdeveloped frequency ranges, even though there are a great number of potential applications in remote sensing, spectroscopy, plasma diagnostics, and communications. This is because the millimeter wave and far-infrared frequency range falls between two other frequency ranges, the microwave frequency range and the near-infrared and optical frequency range, in which conventional semiconductor devices are usually operated.

Professor Hu's laboratory is equipped with various millimeter-wave and infrared sources which can generate coherent and incoherent radiation up to 30 THz. These include Gunn oscillators at W-band frequencies (75-110 GHz); a frequency doubler, tripler, and quadrupler using Schottky diodes at 200, 300, and 400 GHz; an optically pumped farinfrared laser which generates coherent radiation up to 8 T...

متن کاملHigh-speed photodiodes for InP-based photonic integrated circuits.
We demonstrate the feasibility of monolithic integration of evanescently coupled Uni-Traveling Carrier Photodiodes (UTC-PDs) having a bandwidth exceeding 100 GHz with Multimode Interference (MMI) couplers. This platform is suitable for active-passive, butt-joint monolithic integration with various Multiple Quantum Well (MQW) devices for narrow linewidth millimeter-wave photomixing sources. The ...
