Abstract
A light source-unit includes a laser diode, a sub-mount which the laser diode is joined. The laser diode includes an optical generating layer including an active layer which emits laser-light and cladding layers being formed so as to sandwich the active layer. The active layer includes a quantum dot layer including a plurality of quantum dots, which respectively confine movements of carriers in the three-dimensional directions.
