LIGHT-EMITTING SYSTEM PROVIDED WITH AN INTEGRATED CONTROL PHOTOSENSOR AND A METHOD FOR PRODUCING SAID SYSTEM

摘要

The invention relates to a light-emitting system provided with an integrated control photosensor and to a method for the production of said system. The inventive system is particularly suitable for optical connections and comprises a light-emitting electronic component (2) and a lightguide (4) which is used for receiving the light transmitted by the component and is provided with a light input surface (8) arranged in front of the component and reflecting a part of the received light and a photosensor (14), which is integrated into the component and is used for detecting a part of the light transmitted thereby, wherein said photosensor is placed near the component and receives a part of the light reflected by the light input surface. The active layer of the light-emitting electronic component and the photosensor active layer are made of the same material.
