  • Semiconductor light emitting device, optical pickup unit and information recording/reproduction apparatus
    Patent number: 8494020
    Abstract: A semiconductor light emitting device downsized by devising arrangement of connection pads is provided. A second light emitting device is layered on a first light emitting device. The second light emitting device has a stripe-shaped semiconductor layer formed on a second substrate on the side facing to a first substrate, a stripe-shaped p-side electrode supplying a current to the semiconductor layer, stripe-shaped opposed electrodes that are respectively arranged oppositely to respective p-side electrodes of the first light emitting device and electrically connected to the p-side electrodes of the first light emitting device, connection pads respectively and electrically connected to the respective opposed electrodes, and a connection pad electrically connected to the p-side electrode. The connection pads are arranged in parallel with the opposed electrodes.
