  • Device and method for bowtie photoconductive antenna for terahertz wave detection
    Patent number: 11081604
    Abstract: A process of fabricating and a photoconductive antenna are disclosed which include a semi-insulating substrate having a top side and a bottom side; a low-temperature Gallium Arsenide (GaAs) layer deposited on the top side of the semi-insulating substrate; a plurality of metal electrodes having a bowtie dipole, with an excitation gap at the center, deposited directly on the low-temperature Gallium Arsenide layer; and an extended hemispherical lens attached to the bottom side of the semi-insulating substrate; the extended hemispherical lens further comprises an extension layer and a hemispherical layer separated by an extended line whose position is selected so that a beam of light coming from outside of the extended hemispherical lens is collimated to the excitation gap.
