The T-Era-20D40P-1550-fiber terahertz photoconductive antenna (THz-PCA) is used to detect wideband terahertz pulses in terahertz time-domain systems. The T-Era-20D40P-1550-fiber THz-PCA is made on high resistive ultra-fast epitaxially grown multi-quantum well InGaAs-InAlAs substrates and is packaged in TeTechS' patent pending terahertz chip fiber coupled enclosure module. The enclosure module houses the THz-PCA with a collimating high-resistive silicon lens attached to the back side of the THz-PCA chip, an FC/APC fiber connector and optical collimating and focusing lenses. 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.
In the receiving operation mode, the detected THz photocurrent can be measured through the MMCX connector. The standard 01' treaded body makes it convenient to attach the module to other standard optical components or mount it on an optical bench. When excited by optical pulses with 8 mW average optical power, the T-Era-20D40P-1550-fiber THz-PCA generates 200 pA peak terahertz photocurrent with more than 50dB terahertz power spectrum dynamic range.
When excited by 100fs optical pulses with 8mW average power the T-Era-20D40P-1550-fiber THz-PCAs generate 200 pA peak terahertz photocurrent with more than 50dB THz power spectrum dynamic range.
