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.
