iPCA - interdigital Photoconductive Antenna for terahertz waves


Large area broadband antenna with lens array and high emitter conversion efficiency   antenna Picture iPCAp and iPCAs
             iPCAp                           iPCAs  
 

 


iPCA with LT-GaAs absorber, microlens array for laser excitation wavelengths l ú 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.
