Abstract

The optical analog of vacuum triode with electron flow being replaced by photon flow -- optical triode (OT) -- is considered. Distinctions of such a device with respect to vacuum and semiconductor triodes are discussed. As an illustration and example of possible application of OT the design of RF generator without conventional active elements is experimentally demonstrated. The amplification and feedback are realised in optical channel by means of Pockels cell and vacuum photodetector. The application of suggested device as a sensitive photo receiver is discussed.
