Low Divergence Coherently Coupled Vertical Cavity Surface Emitting Laser Ring Arrays
We report the theory and experimental verification of a method to reduce beam divergence from coherently-coupled ring arrays of photonic crystal vertical cavity surface emitting lasers (VCSELs). The photonic crystal etched into the top distributed Bragg reflector defines the optically coupled array...
