Abstract
A bottom-emitting vertical-cavity surface-emitting laser (VCSEL) chip may include a VCSEL array including plurality of VCSELs and an integrated optical element including a plurality of lens segments. The integrated optical element may direct beams provided by the plurality of VCSELs to a particular range of angles to create a diffusion pattern using the beams provided by the plurality of VCSELs. A surface of a first lens segment may be sloped to cause a beam from a first VCSEL to be steered at a first angle and a surface of a second (adjacent) lens segment may be sloped to cause a beam from a second VCSEL to be steered at a second angle. A direction of the second angle with respect to a surface of the VCSEL array may be opposite to a direction of the first angle with respect to the surface of the VCSEL array.
