Semiconductor laser device, distance measurement device, and vehicle-mounted device

Abstract

For example, the technique of the present disclosure reduces inductance between electrodes. Provided is a semiconductor laser device including: a semiconductor substrate having a first principal plane and a second principal plane opposite to the first principal plane; a plurality of light-emitting units disposed on the first principal plane; a first electrode electrically connected to a first region that is one region when an active region of each of the light-emitting unit serves as a boundary; and a second electrode electrically connected to a second region that is the other region when the active region of each of the light-emitting unit serves as the boundary. The first electrode and the second electrode are stacked via an insulating film therebetween on the first principal plane along a thickness direction of the semiconductor substrate.

Dependencies are inferred from the claim text.
