Abstract
This paper reports on the measurement of the relative phase in coherently-coupled in-phase VCSEL arrays and show that the phase can be varied by differential current injection over a full range of π, requiring <; 200 μA, which is several orders of magnitude lower than phase tuning by similar methods in slab-coupled lasers.
