The T-Era-100A-800-Air terahertznphotoconductive antenna (THz-PCA) is used to generate wideband THz pulses innterahertz time-domain systems. The T-Era-100A-800-Air THz-PCA is made on highnresistive ultra-fast epitaxially grown low-temperature GaAs (LT-GaAs)nsubstrates packaged in TeTechS\' patent pending THz chip enclosure module. Thenenclosure module houses the THz-PCA with a collimating high-resistive siliconnlens attach to the back side of the THz-PCA chip.
n
The device is packaged in a modular formatnso that it is easy to change the THz-PCA chip inside the enclosure at anfraction of cost. The device is shipped with the silicon lens aligned andnpackaged on the back side of the THz-PCA chip. The silicon lens can benre-aligned after changing the THz-PCA chip using our silicon lens settingnfixtures.

An input bias voltage can be applied to thenchip through an isolated MMCX connector. The standard 01\' treaded body makes itnconvenient to attach the module to other standard optical components or mountnit on an optical bench.
