Abstract
An optical device such as a radiation detector or an optically activated memory includes a barrier region located between two active regions. One or more quantum dots are provided such that a change in the charging state of the quantum dot or dots affects the flow of current through the barrier region. The charging states of the quantum dot is changed by an optical device.
