Abstract
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.

Jose Carlos D. do Amaral Rocha
Univ. of Exeter (United Kingdom), The Univ. of Queensland (Australia)
He completed his undergraduate and master's degrees at the Federal University of Alagoas in Brazil. During his master's program, he focused on structured light in nonlinear wave mixing, gaining valuable experience in optics and photonics.
Currently, he is pursuing a Ph.D. through a joint program between the University of Exeter and the University of Queensland. His doctoral research centers on applying a multi-plane light converter to address challenges in fibre imaging. This work aims to advance the field of optical imaging techniques, potentially leading to improvements in various applications such as medical diagnostics or telecommunications.
