A semiconductor laser device has a heat sink of which laminated plural plates are constituted and a semiconductor laser element mounted on upper surface of the heat sink. The heat sink has a channel in which a coolant flows inside thereof. The heat sink includes a channel-forming plate portion that forms the channel and a mounting plate portion that forms an upper surface of the heat sink that comes into contact with the channel. The mounting plate portion is made of material having a thermal expansion coefficient, which is nearer that of the semiconductor laser element than that of the channel-forming plate portion.

A method of fabricating a semiconductor light emitting device includes fabricating semiconductor light emitting devices on a large scale by forming desirable end surfaces of resonators using an etching process. The method includes the steps of forming, on a base body, semiconductor layers for constituting a plurality of semiconductor light emitting devices; grooving the semiconductor layers formed on the base body in the direction from a front surface of the semiconductor layers to the base body, to form stripe-like grooves; and forming a semiconductor film in the grooves by epitaxial growth; wherein a side surface of each of the grooves, which side surface finally forms an end surface of a resonator of each of the semiconductor light emitting devices, is a crystal plane being later in epitaxial growth rate than a bottom surface of the groove.

摘要:
The present invention provides a light emitting device solving weakness caused by bonding between first and second light emitting elements and a method of manufacturing the same. A chip-shaped first light emitting element and a second light emitting element overlapped each other are disposed on a supporting base. Four island-shaped projections are provided on the top face of the supporting base, and support the second light emitting element. The projections are formed by wet-etching or dry-etching the supporting base, and a pad electrode is provided on the top face of the projection. The pad electrode is electrically connected to the second light emitting element and is also electrically connected to a wire.
