The T-Era-20D40P-1550-air terahertz photoconductive antenna (THz-PCA) is used to detect wideband THz pulses in terahertz time-domain systems. The T-Era-20D40P-1550-air THz-PCA is made on high resistive ultra-fast epitaxially grown multi-quantum well InGaAs-InAlAs substrates packaged in TeTechS' patent pending THz chip enclosure module. The enclosure module houses the THz-PCA chip with a collimating high-resistive silicon lens attach 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.
The detected terahertz photocurrent can be measured through a 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 18 mW average optical power, the T-Era-20D40P-1550-air THz-PCA generates 250 pA peak terahertz photocurrent with more than 50dB terahertz power spectrum dynamic range.
