>> Large-scale integration of this platform paves the way for fully reconfigurable chip-scale three-dimensional volumetric light projection across the entire visible range.
That's what I thought. Do this a wafer-scale and you have a fully holographic display. Curious how they phase synchronize so many light emitters but the full paper looks like $$
There's only a single light emitter, a fiber laser that feeds the device. That's split in treelike fashion. At each branching part, there's an optical resonator that ensures light is fed evenly to each branch. Each branch has its own phase delay, which requires a bit of software tuning to account for variations.
