A Fully Optoelectronic Continuous-Wave 2-Port Vector Network Analyzer Operating From 0.1 THz to 1 THz

We present a 2-port terahertz vector network analyzer (VNA) based on four continuous-wave (CW) photomixers and pair of telecom-wavelength CW lasers. The presented optoelectronic VNA is free-space coupled can operate continuously from 0.1 THz to 1 with resolution 2 MHz. demonstrate two different applications it: the determination material properties quartz wafer characterization distributed Bragg reflector (DBR).
