A hybrid solution for spatial light modulators with a large space-bandwidth product: opinion

Abstract

Increasing the space-bandwidth product of spatial light modulators incurs severe issues in terms of power consumption, mutual crosstalk, and control signal wiring. In this opinion article, we propose a novel system to overcome these challenges by marrying energy-efficient modulators in photonic integrated circuits (PICs) and a meta-optical beam aggregator. This hybrid approach can significantly improve the space-bandwidth product, theoretically up to 1013 Hz · pixel, which is several orders of magnitude higher than the state-of-the-art.
