Abstract

We present an efficient and compact laser pulse-pumped terahertz (THz) source suitable for on-chip applications. The THz emitter itself consists of a W(1.8 nm)/Fe(2 nm)/Pt(1.8 nm) metallic trilayer deposited via DC magnetron sputtering. Waveguides and a horn antenna are 3D-printed via 3D lithography and integrated with the emitter, resulting in a 19.6 dB increase in the measured THz power emitted at the design frequency of 1.5 THz.
