Abstract
PURPOSE: To obtain an edge emission type light-emitting diode having the excellent temperature characteristics of an optical output by forming an electrode for pulse currents and an electrode for DCs shaped onto a semi conductor layer including an active layer and an injection region and a non-injection region of currents from these electrodes to the active layer.
CONSTITUTION: An N-InP buffer 2, an InGaAsP active layer 3, a P-InP clad 4 and an N-InGaAsP contact 5 are superposed onto N-InP 1, and a P layer 7 reaching the clad 4 is diffused, using an insulating layer 6 as a mask. An electrode 8 for pulses and an electrode 7 for DCs are shaped onto the N layer 5 in order near to the outgoing face of beams, and a section in which there is no electrode on the rear end face side is used as a current non-injection region. An electrode 10 is attached to a substrate 1. An electrode 9 forming section is employed as the absorption region of beams from the active layer, to which pulse currents are injected, when currents are not flowed, and an optical output can be increased or decreased by varying DC currents as pulse currents are left as they are kept constant. Accordingly, an edge emission type LED having the improved temperature characteristics of the optical output is acquired.
