Abstract

PURPOSE:To eliminate the hindrance factors for a normal operation by causing an optical transmission path to be composed of a plurality of laminated semiconductor layers and by forming the semiconductor layers having a narrow forbidden band width into a shape of a quantum well structure which is sandwiched by the semiconductor layers having a large forbidden band width. CONSTITUTION:A single quantum well structure of GaAs/AlxGa1-xAs (x=0.2) is formed on a GaAs structure 11 with a highly controllable molecular beam epitaxy. That is, an optical transmission path 10 which is composed of a quantum well structure where a GaAs crystal layer 13 having a small forbidden band width is sandwiched by GaAlAs crystal layers 12 and 14 having a large forbidden band width is formed. Then, for example, a photosemiconductor device can be formed by combining it with a photosemiconductor element on the basis of a quantum optical principle having a multi quantum well laser. The hindrance factors for normal operations of the photosemiconductor can be eliminated by the use of the optical transmission path having consistency with the photosemiconductor element in this way and the reliability of the device is improved.
