The reflection of light from moving boundaries is of interest both fundamentally and for applications in frequency conversion, but typically requires high pump power. By using a dispersion-engineered ...

Grating couplers are a fundamental building block of integrated optics as they allow light to be coupled from free-space to on-chip components and vice versa. A challenging task in designing any ...

Light readily bounces off obstacles in its path. Some of these reflections are captured by our eyes, thus participating in the visual perception of the objects around us. In contrast to this usual ...

There’s considerable interest in leveraging the bandwidth and other potential virtues of terahertz waves that occupy the spectrum between the conventional RF and optical worlds, generally considered ...

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 ...
