Abstract

Vertical-cavity surface-emitting lasers (VCSELs) and VCSEL arrays having small size and small pitch are provided. Particularly, the present disclosure relates to novel and advantageous chip layouts for ensuring low resistance devices with good yield for small pitch arrays. More particularly, the present disclosure describes approaches for reducing the area consumed by a VCSEL structure so that a higher density VCSEL device may be achieved.
