Our work on AR metasurface on a chip is highlighted on the Cover of Advanced Optical Materials

Optical waveguides are widely used in integrated photonic circuitry for a variety of applications such as on-chip lasers, filters, light sources, amplifiers. Such waveguides suffer from high reflection which harms the transparency of the device and, therefore, its efficiency. In article number 2100130, Alina Karabchevsky and her team from the School of ECE at Ben-Gurion University report a new anti-reflection metamaterial, inspired by Jellyfish anti-reflective eyes, engraved on a waveguide facet experiencing broadband behavior that enhances the waveguide transparency.

Paper entitled 'On-Chip Metasurface-on-Facets for Ultra-High Transmission through Waveguides in Near-Infrared'.
