The TERA8-1 antenna is a single dipole structure mounted on a PCB. The antenna can be used both as an emitter and as a detector. The TERA8-1 antennas are used in the TERA-K8 time domain spectrometer kit.
To obtain the best performance of the TERA8-1 antenna, Menlo Systems offers the T8-H2 mount, which includes a focusing lens for the optical beam and a pre-collimating Si lens for the THz radiation. The T8-H2 mount features an X-Y position adjustment of the Si lens relative to the TERA8-1 antenna and an X-Y differential screw adjustment for precise control of the alignment of the TERA8-1 to the focus of the optical
Terahertz Antennas for 1030 nm
- Optimized for Lasers Around 1030 nm, Pulse Widths <100 fs, 100 MHz Repetition Rate
- Based on Novel Mesa-Structured InGaAs/InAlAs Photoconductive Layers
The TERA10-SL25-FC and TERA10-DP25-FC Antennas feature a polarization-maintaining, fiber-coupled solution for greatest ease of use and optimum performance. The geometries of the emitter and receiver antennas are optimized for best signal-to-noise and bandwidth. The emitter has a strip line geometry and the detector has a dipole geometry (see figure to the right). These “plug and play” antenna modules offer the best flexibility in experimental configuration and setup.
Terahertz Antennas for 1560 nm
- Optimized for Lasers Around 1560 nm, Pulse Widths <100 fs, 100 MHz Repetition Rate
- Patented LT InGaAs/InAlAs on InP Multi-Layer Structure
- Available for Both Free-Space and Fiber-Coupled Inputs
The TERA15-SL25 and TERA15-DP25 antennas, like the TERA8-1 above, are substrates mounted on PCBs. The TERA-SL25 emitter is a stripline geometry, and the TERA15-DP25 is a dipole geometry. Menlo Systems also offers the T15-H2 mount for best performance and easy adjustment of the TERA15 antennas. The T15-H2 includes a focusing lens for the infrared beam and a pre-collimating Si lens for the THz radiation. The T15-H2 mount features an X-Y position adjustment of the Si lens relative to the TERA15 antenna and an X-Y differential screw adjustment for precise control of the alignment of the TERA15 antenna to the focus of the infrared beam.
The TERA15-TX-FC and TERA15-RX-FC antennas are polarization-maintaining, fiber-coupled modules optimized for better THz power production. These antennas are used in the fully fiber-coupled TERA-K15 and TERA-OSCAT terahertz spectrometers.
