Abstract

PURPOSE:To impart a function of monitoring light emitting output to a light emitting diode itself while effectively utilizing light heretofore usually unused, by limiting a conductive converting portion on the surface of a conductive type blocking layer composing a light emitting diode only to the peripheral part of the exposed section of an inverse type conductive layer. CONSTITUTION:An n type InGaAs light emitting layer 2 is grown on an n type InP substrate 1, and a p type InP layer 3 laid thereon. Additionally, an n type In GaAs blocking layer 9 smaller in the energy gap than the layer 2 is grown to produce a p-n junction 12 between it and the layer 3. Then, a window 5 is etched in the center of the layer 9 and an impurity is diffused near the window 5 and the side surrounding it to form an ohmic layer 10 converted to p type so that a p-n junction 13 is produced between it and the layer 9. Thereafter, a back electrode 8 is coated on the back of the substrate 1, a surface electrode 7 on the layer 10, and the third electrode 11 on the layer 9 respectively. A load resistance 14 is connected between the electrodes 7 and 11. This enables the taking out of light other than from the window 5 thereby permitting the monitoring using an potential difference generated in the resistance 14.
