Abstract :
The work has demonstrated both top and bottom emitting coherently coupled VCSEL arrays operating in the preferred in-phase supermode. Moreover, it was shown that phase tuning between the array elements is possible with varying injection current to the array elements. With the bottom emitting arrays, these would be able to scale up the array size, maximum power, and beam steering properties.
