Fast and light-efficient wavefront shaping with a mega-pixel phase light modulator

Phase Light Modulators (PLMs) are a recently developed type of micro-electromechanical system (MEMS)-based Spatial Light Modulator (SLM). PLMs consist of 2D mega-pixel arrays of micromirrors, each of which can be raised or lowered with 4-bit precision at switching speeds of <50 µs. These features mean PLMs have the potential to outperform existing SLM technology in high-dimensional adaptive optics applications. In this work, we demonstrate in-situ aberration correction using a PLM. We characterize and correct the phase curvature of the PLM chip, and demonstrate high-fidelity, high-efficiency, and fast-switched diffractive beam shaping.
