Judiciously distributing laser emitters to shape the desired far field patterns
Constantinos A. Valagiannopoulos, Vassilios Kovanis
The far-field pattern of a simple one-dimensional laser array of emitters radiating into free space is considered. In the path of investigating the inverse problem for their near f…
