iPCAp-21-05-1000-800-h Interdigital photoconductive terahertz antenna with the following parameters:
- Excitation laser wavelength: 800 nm
- Excitation laser pulsewidth: 100 fs typ (femtosecond Ti:Sapphire laser Trestles Finesse)
- Max. mean optical power: 3 W
- Optical reflectance at 800 nm: less than 10%
- Antenna resonance frequency: 2 THz
- Emitted THz spectrum: 0.1 3.0 THz
- Emitter conversion efficiency: 10-4 or better at 0.5 W optical power
- Max. voltage required: 20 V for a safe long time use
- gap distance 5 μm
- active area 1mm x 1mm - mounted on a 25.4 mm diameter aluminum heat sink, with adjusted optical microlens-array on the front side and hyperhemispherical silicon lens on the back side and coaxial cable with BNC connector

Interdigital photoconductive antennas with an active area of 1mm x 1mm, which can be used with mean optical laser power up to 3W, if the mount has a good thermal connection to a larger heat sink to remove the 3W thermal power from the antenna.

New antenna with an larger active area of 3mm x 3mm for mean optical power up to about 10 W with a water cooled mounting will be available November 2008!

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.
