Abstract
A light emitting device includes a substrate, a first light emitting element arranged on the substrate, a second light emitting element arranged on the substrate, and a wiring layer arranged over the first light emitting element and the second light emitting element. Each of the first light emitting element and the second light emitting element is a vertical cavity surface emitting laser (VCSEL) element. The first light emitting element is configured to emit light by being supplied with electric power from the wiring layer. The second light emitting element is configured such that electric power for causing the second light emitting element to emit light is not supplied from the wiring layer to the second light emitting element.
