Abstract:

Existing and emerging applications for terahertz technology motivate the need for improved terahertz sources. With the Submillimeter-wave technology gap, terahertz sources lag the performance found in other regions of the spectrum. Many applications such as imaging, chemical agent detection, and spectroscopy would benefit from narrowing the technology gap. This SBIR focuses on improving key aspects of terahertz sources including power, spectral purity, and noise while maintaining good bandwidth, sweep speed, and size for output frequencies from 0.1-1 Terahertz. For the interim technical report, Virginia Diodes Inc. VDI reported power and bandwidth results for two different sources. One source uses all broadband components to achieve the maximum bandwidth, while the other source uses a mixture of high powered and broadband components to achieve the maximum amount of power over 100 GHz of bandwidth. VDI has delivered the high powered version for completion of phase I. The source operates from 660-760 GHz with greater than 100 microwatts of power.
