The terahertz frequency band, spanning from about 100 GHz through 10 THz, is today the most exciting region of the electromagnetic spectrum for scientists and engineers.VDI will create a compact and easy to use terahertz source. VDI s integrated diode circuits will be used to extend the functionality of advanced microwave technology to the terahertz frequency band. The new source will generate useful power from 100 GHz through at least 1 THz and will be ideal for research laboratories striving to develop new applications of terahertz technology in fields including chemical and bioagent detection, personnel imaging to detect concealed weapons and explosives, short range secure communications and collision avoidance systems. It will meet all of the requirements described in the solicitation. In addition, it will allow frequency resolution of better than 1 kHz, generate milliwatt power levels at 200 GHz and at least 10 microwatts at 1 THz. It will also be compact, power efficient and adaptable for portable use and extendable to higher frequencies. Most importantly it will be cost efficient enough for a broad array of applications, including basic research facilities and university education laboratories.
