Abstract: A semiconductor device according to the present disclosure includes an electrically conductive first electrode block, an electrically conductive submount, an insulating layer, a semiconductor element, an electrically conductive bump, and an electrically conductive second electrode block. The submount is provided in a first region of the upper surface of the first electrode block, and electrically connected to the first electrode block. The semiconductor element is provided on the submount, and has a first electrode electrically connected to the submount. The bump is provided on the upper surface of a second electrode, opposite the first electrode, of the semiconductor element, and electrically connected to the second electrode. A third region of the lower surface of the second electrode block is electrically connected to the bump via an electrically conductive metal layer. An electrically conductive metal sheet is provided between the metal layer and the bump.

Abstract: A laser module according to the present disclosure includes a laser diode, a first collimating lens, and a beam twister. The laser diode includes a plurality of emitters and emits laser light from each of the plurality of emitters through a light emission surface. The first collimating lens is provided at a first distance from the light emission surface of the laser diode and parallelizes a fast-axis-wise divergence of the laser light. The beam twister is provided at a second distance away from the first collimating lens and turns the laser light approximately 90 degrees. Each of the plurality of emitters has a width of 5 μm to 120 μm on the light emission surface. The plurality of emitters have a pitch of 295 μm to 305 μm on the light emission surface.
