Abstract
We propose and experimentally demonstrate a holographic technique based on interfering the optimum orthogonal communication modes connecting a source plane and a receiver volume. Computing the singular value decomposition of a coupling operator, which connects each point at the source plane to another one in the receiver volume, allows us to obtain a complete set of orthogonal eigenfunctions which represent the building blocks of our hologram. By adding these eigenfunctions, weighted by different complex coefficients akin to a Fourier series, we construct arbitrarily chosen 2D and 3D images within the output receiver volume with continuous depth, high fidelity and contrast. We envision our work to inspire new directions in digital holography, AR/VR, and wearable devices.

Dr. Dorrah is an Assistant Professor in the department of Applied Physics and Science Education at Eindhoven University of Technology, The Netherlands. Before then he was a research associate in the School of Engineering and Applied Sciences (SEAS) at Harvard University, working in the areas of Structured Light and Flat Optics. He obtained his MASc (2015) and PhD (2019) degrees, both from the University of Toronto, in Electrical and Computer Engineering. During his PhD, he joined Lawrence Berkeley National Lab (LBL) in California and the University of the Witwatersrand in South Africa as a visiting research scholar. Dr. Dorrah’s research interest covers the wide area of light-matter interaction, structured light, and flat optics. He is currently developing compact devices which can manipulate light at the nanoscale for possible application in remote sensing, micromanipulation, biological imaging, and free space optical communications.
