Abstract
A plurality of vertical-cavity surface-emitting laser devices each having a different lasing wavelength are arrayed by a simple structure and a manufacturing process without increasing device resistance. Each vertical-cavity surface-emitting laser device comprises a layered structure including an active layer and a current confinement layer. The area of current confinement portion in the laminate structures is set corresponding to a wavelength of laser light emitted from each vertical-cavity surface-emitting laser device. Thereby, the plurality of vertical-cavity surface-emitting laser devices emits laser light with different lasing wavelengths.
