Neural networks

An opto-electronic component comprises a substrate of InP (4, 5) with stacks of quantum wells (6) grown on both surfaces of the substrate. Layers (7) of n doped InP having p-doped regions (8) are formed on the outer surface of the quantum well structures. In use, voltages V1 and V2 may be applied to electrodes (1) enabling the component to be used for a number of applications, e.g. as a detector/modulator pair, in close coupled arrays of modulators, etc.
