Coherence in Multielement-Phased Vertical-Cavity Surface-Emitting Laser Arrays Using Resonance Tuning

We show that optical coupling can be achieved reproducibly and with high yield by resonance tuning the elements of substrate-emitting and top-emitting vertical-cavity surface-emitting laser arrays. The resonance tuning is enabled by electrical isolation of the lasing elements in the array, which in...
