Customer Reviews For The Terahertz Large Aperture Free Beam Sensor - 1550nm/400um
The TeTechS T-Era series terahertz photoconductive antenna chips (THz-PCA) are used to generate high power and wideband terahertz pulses in terahertz time-domain systems as well as high frequency resolution terahertz signals in terahertz frequency domain systems. The T-Era-400A-1550-Air THz-PCA is made on high resistive ultra-fast epitaxially grown multi-quantum well InGaAs-InAlAs substrates and is packaged in TeTechS' patent pending THz chip enclosure module. The antenna structure is a 400um aperture to generate high bandwidth THz signal. The enclosure module houses the THz-PCA with a collimating high-resistive silicon lens attached to the back side of the THz-PCA chip.
The device is packaged in a modular format so that it is easy to change the THz-PCA chip inside the enclosure at a fraction of cost. The device is shipped with the silicon lens aligned and packaged on the back side of the THz-PCA chip. The silicon lens can be re-aligned after changing the THz-PCA chip using our silicon lens setting fixtures.
An input bias voltage can be applied to the chip through an isolated SMA connector. A built-in voltage limit circuit prevents overvoltage damage to the chip. A standard 01' treaded sleeve of the enclosure make it convenient to attach the module to other standard optical components or mount it on an optical bench.
