  • Semiconductor optical device having a heterointerface therein
    Patent number: 5324959
    Abstract: A semiconductor device includes a region in which carriers are transferred in the lamination direction of a multiple quantum well, such as a multiple quantum well multiplication layer of a superlattice APD. A superlattice structure with a varying well width is introduced to a hetero-interface present in the transfer region, thereby preventing pile-up of the carriers.
