Figure | Next-Generation Terahertz Systems via 3D Printing. a, Concept of an integrated terahertz system, comprising an optoelectronic THz signal source connected to an amplifier via a 3D-printed "bridge" (THz interconnect, TIC), and an elevated THz antenna (TA) that efficiently emits the signal into free space. The top portion illustrates a custom 3D-printed probe (THz probe, TP) used for testing such microscopic circuits. b, THz interconnect: A microscope image of a 3D-printed "bridge" seamlessly connecting THz transmission lines across separate chips. c, THz probe: A microscope image of a 3D-printed testing probe. The structure is shown upside down for better visibility. d, THz antenna: A microscope image of the 3D-printed antenna. By elevating the structure above the underlying substrate, the antenna can radiate signals much more efficiently.
