1.55 μm photoconductive THz emitters based on ErAs:In0.53Ga0.47As superlattices

ErAs:In0.53Ga0.47As superlattice THz emitters are fabricated and characterized at an excitation wavelength of 1.55 µm. Photocurrent-voltage characteristics, carrier lifetimes and bandwidth of the THz output are discussed as a function of the superlattice period.
