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 illumination source. To address this issue, custom optics are employed for incoherent power combining, and subsequently utilized in a demonstration of terahertz imaging.
