A photoconductor for emitting and/or receiving electromagnetic waves is provided. The photoconductor comprises a material region comprising a first and a second section, wherein the second section provides a higher density of charge carrier trapping centers and/or recombination centers than the first section, and a confinement generating a sub-band structure of the charge carrier energy states in the material region. The first and the second section are arranged and configured in such a manner that a maximum of the carrier probability density of the sub-band ground state is located in one of these sections and a maximum of the carrier probability density of an excited sub-band state is located in the respective other section.
