Microelectromechanical system (MEMS) optical modulators are crucial in next-generation technologies such as free-space ...

Quasi-phase-matching (QPM) is crucial in nonlinear optical processes by compensating for phase velocity mismatch. Here, the authors demonstrate a spatiotemporal QPM grating by all-optical poling ...

Abstract: In this work, all-optical Bragg grating filters using Au-MOFs/SU-8 waveguides are achieved based on photothermal effect. This featured loading and network structure of Au-MOFs/SU-8 could ...

The quote conveys a profound idea on which optical illusion tests are premised. Your interpretation of a certain image determines your personality traits. Similarly, to conclude whether you are an ...

(PRESS RELEASE) ALEXANDRIA, VA — The Vision Council continues to provide its members with timely information and critical resources regarding tariffs and their potential impact on the vision and ...

Love flowers? Then you’re in for a treat. We’re not handing out bouquets today, but we are challenging your eyes with a vibrant visual puzzle. This brainteaser, created by McLuck, is an ...

To address these issues, we introduce an innovative, non-invasive sensor made of a deformable optical grating sensor patch. This sensor allows for real-time acquisition of arterial pulse waveforms at ...

Tying light from lasers into stable 'optical knots' Interference patterns between overlapping laser beams could transmit encoded information over thousands of feet through chaotic environments ...

With enough planning, you could get that mesh point to form complex shapes in 3D on demand. A computational representation of an optical knot. The green areas are where the laser light is passing ...
