Abstract

Closely packed VCSEL arrays phase lock due to active lateral interactions from cross gain and cross hole-burning. Breaking the lattice symmetry either by geometry, or by staggered application of two biases IA, IB creates a "two cavity species" photonic lattice. The relative phase among locked cavities is controlled by the applied bias ratio IA/IB. While uniform arrays allow only in- or out- of phase locking, two-species lattices allows a small but continuous range of phase shifts for the Bragg steering condition, without movable parts.
