Abstract
An integrated semiconductor light-emitting device suitable for being mounted on a pickup is provided. The integrated semiconductor light-emitting device has a first laser part stacked on a semiconductor substrate and a projection-shaped second laser part formed by stack in thin-film-layer form. The second laser part is fitted into a trench formed adjacent to the first laser part in the semiconductor substrate. At least the first and second laser parts and the trench are bonded together through a metal bonding layer. An emission spot of the first laser part and an emission spot of the second laser part are located away in approximately the same horizontal direction perpendicular to the direction of the stack of the first and second laser parts.
