Programmable optical interconnections by multilevel synthetic acousto-optic holograms.
Reconfigurable high-fidelity, high-efficiency weighted optical interconnection patterns are demonstrated for the first time to our knowledge with the aid of optimized multilevel phase gratings achieved electronically as phase-modulated sinusoidal refractive-index variations propagating in an acousto-optic Bragg cell.
