Coherent laser arrays from bottom-surface vertical-cavity surface-emitting lasers
Vertical-cavity surface-emitting lasers (VCSELs) are among the best choices for high beam quality semiconductor lasers. By designing a VCSEL array for uniform current injection and having the output coupler on the substrate side of the laser cavity, the laser will more easily operate in the …

Coherently-coupled vertical-cavity laser arrays
Coherently-coupled vertical cavity surface-emitting laser (VCSEL) arrays offer a unique approach to beam steering and high-radiance applications, and have many advantages such as small size, low cost, high speed, durability and manufacturing ease. Previous work on coherently-coupled VCSEL arrays …
