Our fiber coupled TERA15-FC antenna modules for 1560 nm laser wavelength are the unique solution for flexible and robust all-fiber THz-TDS systems. The high-power antenna technology is based on InGaAs/InAlAs multilayered mesa structures with high voltage biasing of the emitter. For highest THz bandwidth we provide optimized structures for emitter and detector. The polarization maintaining (PM) coupling fiber ensures reliable and stable operation even under harsh environmental conditions.
