The T-Era-100A-1550-fiber terahertz photoconductive antenna (THz-PCA) is used to generate wideband terahertz pulses in terahertz time-domain systems. The T-Era-100A-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. When excited by 100fs optical pulses with 14mW average power the T-Era-100A-1550-fiber THz-PCAs generate 200 pA peak terahertz photocurrent with more than 50dB THz power spectrum dynamic range.
