Abstract
A laser diode includes: a plurality of strip-shaped laser structures arranged in parallel with each other, and including a lower cladding layer, an active layer, and an upper cladding layer in this order; a plurality of strip-shaped upper electrodes singly formed on a top face of the respective laser structures, and being electrically connected to the upper cladding layer; a plurality of wiring layers being at least singly and electrically connected to one of the respective upper electrodes; and a plurality of pad electrodes formed in a region different from that of the plurality of laser structures, and being electrically connected to one of the respective upper electrodes with the wiring layer in between. The respective wiring layers have an end in a region different from a region where the respective wiring layers are contacted with the upper electrode.
