Abstract
A signal transmission protected against undesired quering is made possible with a photon-driven component and the energy supply is independent of external electrical connection. A photon-driven device has a light-receiving, monolithic semiconductor component for receiving optical energy and an optical signal for conversion into electrical energy and an electrical signal and has a light-transmitting semiconductor component for converting the electrical signal into an optical signal and for transmitting the optical signal. A radiation source for producing the optical energy and the optical signal and an optical receiver for the output optical signal from the photon-driven component are provided in a device for reading the information carried by the optical signal and produced in an electrical circuit connected to, powered by and operated by the photon-driven semiconductor component.
