Diffuse Beam with Electronic THz Source Array
An array of terahertz sources in 0.13 μm SiGe BiCMOS has previously been developed to mitigate the well-known issue of low available power from compact terahertz sources. However, the device projects beams toward different, non-overlapping directions, rendering it unsuitable for use as a general-purpose…

Incoherent Power Combining of THz Source Arrays
In this paper, we investigate the multi-chip scaling of a previously developed incoherent 4×4-pixel 0.53-THz 1mW source array, implemented in a 0.13-μ m SiGe BiCMOS technology. A standalone module under-samples the illumination space due to a large pixel pitch given by the implemented triple-push oscillator…

Incoherent, spatially-mapped THz spectral analysis
We employ a lens-coupled CMOS terahertz camera to measure the dispersion of an inexpensive reflective diffraction grating. Thus, although the terahertz camera was originally intended for terahertz imaging applications, we show that it can be re-purposed to perform spectral analysis. Two different experiments…

Terahertz spectroscope using CMOS camera and dispersive optics
There is a need to reduce the cost and size of functional terahertz devices, in order to expedite this notoriously under-utilized frequency band toward practical applications. Electronic integrated circuits (ICs) are extremely useful to this end, as they provide a means to achieve miniaturization and…
