Polychromatic digital optics for structured light

Project description

A high-efficiency spatial light modulator in the visible spectrum

Spatial light modulators are a class of optical devices that impose some form of spatially-varying modulation on a light beam. State-of-the-art devices operate efficiently only at a given wavelength. Funded by the Marie Skłodowska-Curie Actions programme, the BB-SLM project plans to develop a digitally controlled spatial light modulator that will demonstrate high efficiency in the whole visible spectrum. To achieve its goal, the project will combine an achromatic geometric phase shifter with circular Bragg reflection from spatially modulated chiral liquid crystals. The inherently robust topological structures that spontaneously appear in soft matter systems, such as liquid crystals, allow controlling the interaction between the polarisation state of light and its spatial degrees of freedom.
