Single element coplanar strip-line photoconductive (PC) emitters remain to date the most common means of generating an detecting sub-picosecond terahertz radiation. These antennas however, suffer from excitation power limitations leading to relatively early saturation. It is possible to overcome such limitations by using several radiating elements arranged as an array. We present an array structure...
We report on a technique to perform broadband near-field optical microscopy (ANSOM) in the THz domain, in which all components of the THz near-field are measured directly using electro-optic detection in GaP electro-optic crystals with a focused near-IR probe beam. The spatial resolution of our technique is much smaller than the THz wavelengths. This enables us to measure with great accuracy the time-dependent...
We present a novel epitaxial lift-off technique for the fabrication of THz antenna array structures on low temperature grown (LT) GaAs. The radiated electric field of the array shows an increase compared to single element emitters, due to the constructive interference of the individual array elements in the emitter far-field. We have demonstrated this emitter in pulsed THz operation, however simulations...
