Reconfigurable semiconductor laser networks based on diffractive coupling
Daniel Brunner, Ingo Fischer · Optics Letters · 2015
Networks of optical emitters are highly sought-after, both for fundamental investigations as well as for various technological applications. We introduce and implement a novel scheme, based on diffractive optical coupling, allowing for the coupling of large numbers of optical emitters with adjustable weights. We demonstrate its potential by coupling emitters of a 2D array of semiconductor lasers with significant efficiency.
