“…Numerous attempts have been made to make use of the mature Er-doped femtosecond fiber lasers at 1550-nm wavelength, which corresponds to InGaAs based photoconductive antennas. [4][5][6][7][8][9] However, great potential remains for further development to improve the PCA output power and efficiency. In recent years InGaAs/InAlAs multilayer heterostructure (MLHS) grown by MBE has been proved to have high optical conversion efficiency, low noise level and rather broad THz band emission.…”

A mesa-type enhanced InGaAs/InAlAs multilayer heterostructure (MLHS) terahertz photoconductive antenna (PCA) at 1550 nm is demonstrated on an InP substrate. The InGaAs/InAlAs superlattice multilayer heterostructures are grown and studied with different temperatures and thickness ratios of InGaAs/InAlAs. The PCAs with different gap sizes and pad sizes are fabricated and characterized. The PCAs are evaluated as THz emitters in a THz time domain spectrometer and we measure the optimized THz bandwidth in excess of 2 THz.

The study of the interaction between terahertz (THz) radiation and quantum materials has been an active area of research due to its potential for understanding fundamental physics and the development of novel technologies. In this review, we focus on the time-dependent photocurrents, behind which are the up-to-date understanding of the physical processes. We provide the recent advancements in revealing the unique properties of quantum materials via the THz emission spectroscopy. Because the theoretical interpretation of some new experimental results is still evolving, this review is intended to inspire further research in this exciting and rapidly growing field.
