摘要：
Semiconductor heterostructures may be employed for the purpose of light demultiplexing. The structure consists of a series of potential wells at discrete energy gaps, which can be achieved by either a compositional variation or, in addition, an external electric field. Incident radiation is demultiplexed as a result of selective absorption at different wavelengths at these wells, creating carriers which can be detected from lateral conductivity.
