Mechanical tests show that these optoelectronic characteristics remain stable under repeated bending, confirming that wavelength selectivity, sensitivity, and flexibility can coexist in a single ...

Researchers at the U.S. National Institute of Standards and Technology have built a compact laser system that suppresses frequency noise by more than 140 decibels, a performance level that could ...

The laser module is one of the least reliable components in such a system. For that reason, it remains in a convenient ...

Hai “Helen” Li studies neuromorphic computing and AI hardware from a design and computer architecture perspective.

Lasers, devices that emit intense beams of coherent light in specific directions, are widely used in research settings and are central components of various technologies, including optical clocks (i.e ...

When light passes through materials, it typically changes direction and bends in predictable ways. This change in direction, known as refraction, is caused by a change in the speed of light as it ...

Your TV may have a port labelled for optical audio, but it's a sorely underused port that most consumers may not even realize ...

Abstract: Deep-learning-based face recognition (FR) systems are susceptible to adversarial examples in both digital and physical domains. Physical attacks present a greater threat to deployed systems ...
