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 of flexibility 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 electric field amplitude).

To achieve the highest THz bandwidth possible, the structures for both the emitter and detector components have been carefully optimised. Moreover, our polarization-maintaining (PM) coupling fiber enables a reliable and stable operation, even when faced with harsh environmental conditions.

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.

TERA15-TX-FC measurement settings: 100 V bias with 25 mW optical powers at 24 Hz scan speed to achieve >6 THz and >95 dB in 60 sec
TERA15-HP-TX measurement settings: 200 V bias with 50 mW optical powers at 24 Hz scan speed to achieve >4.5 THz* and up to 110 dB in 60 sec
All measurements were conducted under ambient conditions without purging

*Some high-power-enabled systems achieve a lower usable bandwidth when operated at maximum field strength due to saturation effects in the detector washing off some phase information above 4.5 THz.
