TL;DR: In this paper, a significant improvement of modulation bandwidth from 2 × 1$ photonic crystal vertical-cavity surface-emitting laser arrays was achieved by control of injection bias conditions to array elements.

TL;DR: In this article, the parity-time symmetry breaking in an electrically injected, coherently coupled, vertical cavity surface emitting laser arrays was shown to be possible in terms of beam steering, mode evolution, and mode hopping as a consequence of the non-Hermiticity of the array analyzed by temporal coupled mode theory.

TL;DR: In this paper, the parity-time symmetry breaking in an electrically injected, coherently coupled, vertical cavity surface emitting laser arrays was reported, with quantitative agreement with the temporal coupled-mode theory with both an asymmetric gain distribution and local frequency detuning.

TL;DR: In this paper, the modulation properties of two-element photonic crystal ion-implanted coherently coupled vertical cavity surface emitting laser arrays emitting at 850 nm are reported, where the phase detuning and injection ratio between array elements are critical parameters influencing modulation bandwidth.

TL;DR: In this article, the authors demonstrate that these arrays can be electronically tuned to coherently coupled operation and at bias conditions not previously realized, with the result that the phase relation and coherence of the array can be engineered.
