Menlo Systems’ fiber-coupled TERA15-FC antenna modules for 1560 nm lasers enable flexible, robust all-fiber THz time-domain spectroscopy (THz-TDS) systems. The high-power antenna technology is based on multilayered InGaAs/InAlAs mesa structures that provide high-voltage biasing of the emitter. The emitter and detector structures are optimized for high THz bandwidths. A polarization-maintaining (PM) coupling fiber ensures reliable and stable operation even under harsh environmental conditions.
