Abstract

There are various applications in high voltage or explosive environments, where sensor powering as well as data transmission has to be electrically isolated. A possible solution can be based on optically powered optical sensor links. These links need typically four different optical components: For the data communication a fast LED as a transmitter and a photo diode as a receiver, furthermore for sensor feeding a high-power light source and a photonic power converter. In this paper it will be demonstrated how to realize an optically powered optical sensor link, using one kind of optical component only, strictly speaking LEDs, for all these tasks.
