On the emitter side the substrate lens supports the THz radiation to escape from
the antenna GaAs substrate and shapes the THz beam.
On the detector side the substrate lens collects the incoming THz radiation and
focus it on the receiving antenna.
Using patented aspheric focusing or collimating substrate lenses no further
THz mirrors or lenses are needed for THz beam shaping.

iPCA - interdigital Photoconductive Antenna for terahertz waves Large area broadband antenna with lens array and high emitter conversion efficiency iPCA with LT-GaAs absorber, microlens array for laser excitation wavelengths l £ 850 nm, adjusted hyperhemispherical silicon lens with a high power conversion efficiency of 0.2 mW THz power / W optical power. The iPCA can be used also as large area THz detector. The two types iPCAp and iPCAs have the same active interdigital antenna area but different contact pad directions with respect to the electrical THz field.
