摘要： An optical scanning device includes a control unit, a light deflector, light detection units, and a light source. A mirror unit of the light deflector has a flat reflection part for generating scanning light and a groove-shaped reflection part for generating twice reflected light, and performs reciprocating rotation about a rotation axis. The light detection units are disposed at positions on the scanning trajectory of the scanning light where the twice reflected light is received, and are each divided into light detectors in the scanning direction of the scanning light by a division line. The control unit detects the deflection angle θ of the mirror unit based on both the output of the light detector and the output of the light detector.

摘要： A vertical cavity light-emitting element includes a substrate, a first multilayer reflector, a semiconductor structure layer, an electrode layer, and a second multilayer reflector. The semiconductor structure layer includes a first semiconductor layer of a first conductivity type on the first multilayer reflector, a light-emitting layer on the first semiconductor layer, and a second semiconductor layer of a second conductivity type on the light-emitting layer. The electrode layer is on an upper surface of the semiconductor structure layer and is electrically in contact with the second semiconductor layer in one region of the upper surface. The second multilayer reflector covers the one region on the electrode layer and constitutes a resonator with the first multilayer reflector. The semiconductor structure layer has one recessed structure including one or a plurality of recessed portions passing through the light-emitting from the upper surface in a region surrounding the one region.

摘要： A semiconductor light-emitting device includes: a substrate having a wiring electrode; a semiconductor light-emitting element mounted on the wiring electrode and having a light-emitting functional layer with an upper surface exposed; a wavelength conversion plate mounted on the light-emitting functional layer and being made of a sintered body including fluorescent material particles and binder particles; and an adhesive layer including a resin medium for adhering a light-incident surface of the wavelength conversion plate to a light output surface of the light-emitting functional layer, and resin particles dispersed in the resin medium. The light-incident surface can expose a sintered surface of the sintered body with a concave portion, and the resin particles are fitted in the concave portion and compressively deformed. The semiconductor light-emitting device is capable of reducing the heat generated from the wavelength conversion plate and of maintaining the high light output.

摘要： A surface emission laser formed of a group III nitride semiconductor includes a first conductivity type first clad layer; a first conductivity type first guide layer on the first clad layer; a light-emitting layer on the first guide layer; a second guide layer on the light-emitting layer; and a second conductivity type second clad layer on the second guide layer. The first or second guide layer internally includes voids periodically arranged at square lattice positions with two axes perpendicular to one another as arrangement directions in a surface parallel to the guide layer. The voids have a polygonal prism structure or an oval columnar structure with a long axis and a short axis perpendicular to the long axis in the parallel surface, and the long axis is inclined with respect to one axis among the arrangement directions of the voids.
