iPCA working principleAn extended gap along the finger electrodes of the iPCA isilluminated by a short pulse laser beam. By using the microlens arrayonly every second gap between the finger structure is excited by thelaser. The fill factor of the lens array of 73.5 % ensures, that nearlythe total optical laser energy is used for excitation of carriers. Despiteof the large emitting area the needed voltage for the carrier excitationis low (< 35 V) because of the small gap of only 5 μm.The coherent excitation of the single emitters located at everymicrolens spot results in a constructive interference of the radiatedTHz waves in the far field.




Mounting:

iPCA chip, size 4 mm x 4 mm, thickness 625μm, mounted on 25.4 mm diameter black aluminium mountwith prealigned hyperhemispherical silicon lens ? 12 mm and prealigned fused silica lens array, size2 mm x 2 mm, and 1 m coaxial cable (RG 178) with BNC or SMA connector.
