A mesa-type enhanced InGaAs/InAIAs multilayer heterostructure (MLHS) terahertz photoconductive antenna (PCA) at 1550 nm is demonstrated on an InP substrate. The InGaAs/InAIAs superlattice multilayer heterostructures are grown and studied with different temperatures and thickness ratios of InGaAs/InAIAs. 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. 展开更多
