摘要:
A semiconductor light emitting device includes a nitride semiconductor layer including a first cladding layer, an active layer, and a second cladding layer, and a current blocking layer configured to selectively inject a current into the active layer. The second cladding layer has a stripe-shaped ridge portion. The current blocking layer is formed in regions on both sides of the ridge portion, and is made of zinc oxide having a crystalline structure.

An optical irradiation apparatus includes: a light-emitting device configured to emit a plurality of light beams whose optical axes extend in a substantially identical direction; a collimator part configured to convert the light beams into parallel light beams; and a light condensing part configured to collect the parallel light beams. The light-emitting device includes a super luminescent diode array in which a plurality of waveguides are provided on a substrate. Each of the waveguides has a light-emitting facet including a light emission point from which an associated one of the light beams is emitted. The light emission points are located in a plane. The plane including the light emission points is orthogonal to a direction of an optical axis of the collimator part.

A laser module includes a substrate 1, a first laser element 2 placed on the substrate 1, a second laser element 3 placed with an output surface opposed to the first laser element 2 on the substrate 1, and a mirror 7 placed between the first laser element 2 and the second laser element 3. The mirror 7 has a reflective surface capable of reflecting output light from the first laser element 2 or the second laser element 3 in a predetermined direction, and is placed so as to move or rotate between a first position capable of reflecting the output light from the first laser element 2 and a second position capable of reflecting the output light from the second laser element 3. Thus, a laser module can be provided in which high precision, low cost, and miniaturization can be realized.
