A new technical paper, “Reduced-crosstalk antennas for grating-lobe-free and wide-field-of-view integrated optical phased arrays,” was published by researchers at MIT. “Integrated optical phased ...

2026 is an exciting time for smart glasses, with several products expected to be launched from big tech players later this year, which will follow Meta's release of the Ray-Ban Display launched in ...

Abstract: This communication proposes a novel filtering antenna design methodology that integrates a slow-wave structure with a double-grating waveguide (DGWG), forming an all-metal structure with ...

This article evaluates some of the strengths and weaknesses of reflective and diffractive waveguides used in augmented reality (AR) optics for smart glasses. Waveguides are the optics used in smart ...

Researchers have designed and demonstrated stretchable waveguides that maintain efficient, stable signal transmission of surface plasmon polaritons even when bent, twisted or stretched. These ...
