Introducing our groundbreaking TERA15 antenna modules, specifically designed for 1560 nm
laser wavelength in all-fiber THz-TDS systems. These modules boast an exceptional blend offlexibility and robustness, making them the unparalleled choice in the market.
The high-power antenna technology employed in these modules relies on InGaAs/InAlAs multilayered mesa structures with the added advantage of high-voltage biasing of the emitter. This
unique approach ensures unparalleled efficiency and performance (up to 3-fold THz electricfield amplitude).
To achieve the highest THz bandwidth possible, the structures for both the emitter and detector components have been carefully optimized. Moreover, our polarization-maintaining (PM)coupling fiber enables reliable and stable operation, even when faced with harsh environmentalconditions.
We currently offer standard emitters (TERA15-TX-FC) and receivers (TERA15-RX-FC) as well as
new high power emitters (TERA15-HP-TX).
In summary, our fiber-coupled TERA15 antenna modules represent a new era in THz-TDS
systems, setting the standard for performance, flexibility, and durability in the industry.
