1. An additive manufacturing system, comprising:
a laser to form a laser beam at a first wavelength; and
a 2D patternable light valve having a resonance based structure responsive to a write beam to pattern the laser beam based on a pattern of the write beam,
wherein the resonance based structure includes an electro-optically activated control structure that imposes an activation of a control layer in a resonator of the resonance based structure, quantum dot materials, or metamaterials.
