摘要
Provided is a VCSEL array device (20) that includes at least a first multilayer reflective film, an active layer, and a second multilayer reflective film, formed on a substrate (22) that extends in a longitudinal direction. Plural mesa portions (24) are formed on the substrate by selectively removing at least a portion of the first multilayer reflective film, active layer, and second multilayer reflective film. A selectively oxidized region is formed in at least one of the first multilayer reflective film and the second multilayer reflective film. The VCSEL array device further includes an interlayer insulating film that covers at least a side portion and a bottom portion of the mesa portions, and a surface protecting film (32) that covers the interlayer insulating film. The surface protecting film (32) has plural grooves (30) formed along a longitudinal direction of the substrate in which at least a portion of the surface protecting film is removed.
