iPCA™ - interdigital photoconductive antenna for terahertz waves

large area broadband antenna with lens array and high THz emitter conversion efficiency

iPCA

l - length, defines the THz resonance frequency
g - gap distance
w - antenna with

iPCA is a trademark of BATOP GmbH registered under the number 30 2008 027 538 at the Deutsches Patent- und Markenamt in Germany.

The iPCA comes with a microlens array for laser excitation and adjusted hyperhemispherical silicon lens. For pulsed laser excitation the power conversion efficiency is as high as 0.1 mW THz power / W optical power. The iPCA can be used also as large area THz detector.
