Hologram wavefront shaping by a nonlinear electro-optic spatial light modulator

25 April 2023 • 11:30 - 11:50 CEST | Zodiac

Abstract

We present a novel waveguide-based approach that enables custom wavefront shaping and holography by employing a non-linear electro-optic spatial light modulator. The device consists of a metamaterial electrode cladding that modulates the Barium Titanate waveguide on a sub-wavelength scale. Our generic modulation principle employs electric fields and non-linear optics to create any desired wavefront and is applicable to Pockels and Kerr cells as well as liquid crystals. Here, we present the operation of our tunable waveguide based SLM, specifically for its use as high-quality holographic display.

Guillaume Croes is currently a PhD researcher at the KUL and imec, Leuven, Belgium. He earned his Bachelor of Science at Hasselt University in 2016, and his Master of Science at University of Technology Eindhoven in 2018. During his master thesis, he worked at imec under supervision of prof. J. Genoe on perovskite light emitting diodes. Afterwards, he started a PhD on holography with prof J. Genoe, closely aligned with his ERC advanced grant titled “Metamaterials for videoholography”. In 2019, he was granted a strategic basic research PhD Fellowship by Fonds voor Wetenschappelijk Onderzoek (FWO).
