The electric field controlled bulk-like optical second-order susceptibility χ(2) in thicker (Si5Ge5)100 superlattices is reported. The relation between χ(2) and the broken structural symmetry by applied external field was observed. The measured large value of χ(2) for (Si5Ge5)100 superlattices is evaluated to be ∼5×10−6 esu with the external field of 100 kV/cm, which indicates that (Si5Ge5)100 superlattices have potential applications in optoelectronic devices.
