摘要: In recent years, additive manufacturing has experienced rapid growth, due to its inherent capabilities for creating arbitrary 3-D structures, accessibility, and associated low costs. This paper first reviews the state of art in printing terahertz (THz) applications identifies critical features required such applications. The future potential this technology is demonstrated experimentally with 3-D-printed, optically controlled THz IQ vector modulator. Here, miniature high-resistivity silicon implants are integrated into metal-pipe rectangular waveguides. 3-D-printed split-block assembly also houses two packaged infrared laser diodes a heat sink. measured performance proof-of-principle 4-quaternary amplitude modulation (4-QAM) modulator that operates up 500 GHz reported. new hybrid technology, which combines semiconductor devices potentially low-cost, high-performance passive guided-wave structures represents paradigm shift may prove be an ideal solution implementing affordable transceivers ubiquitous
