Semiconductor laser element
Abstract:
A semiconductor laser element that includes a stripe-shaped light-emitting region and that is formed by adhering a surface of the semiconductor laser element on a side opposite to a semiconductor substrate and a submount to each other by a solder layer includes a terrace section on a surface of the semiconductor laser element that is adhered by the solder layer, the terrace section being separated from a ridge portion, which is a current-carrying portion, by a grooved portion. A top surface of a region including the grooved portion is covered by a metal. The terrace section is divided into a plurality of portions that are disposed in a scattered manner.
