Abstract
A vertical cavity surface emitting laser (VCSEL) device may include a substrate layer and a first set of epitaxial layers, for a first VCSEL, disposed on the substrate layer. The first set of epitaxial layers may include a first set of mirrors and at least one first active layer. The VCSEL device may include a second set of epitaxial layers, for a second VCSEL, disposed on the first set of epitaxial layers for the first VCSEL. The second set of epitaxial layers may include a second set of mirrors and at least one second active layer. The first VCSEL and the second VCSEL may be configured to emit light in a light emission direction. The at least one first active layer of the first VCSEL may be offset in the light emission direction from the at least one second active layer of the second VCSEL.
