Lasers find applications across several fields ranging from telecommunications and remote sensing to medicine. There are many ways in which one can generate laser emission, or lasing, from a device or ...

More efficient chips based on plasmonics are a step closer to reality through better control of the directional excitation of plasmons in a gold grating. More efficient chips based on plasmonics are a ...

During rapid eye movements, motion of the stationary world is generally not perceived despite displacement of the whole image on the retina. Here we report that during saccades, human observers sensed ...

Scientists from the UK and China have developed a lateral-graded multilayer grating that addresses a key challenge in tender X-ray RIXS technique. Demonstrated at the I21 beamline in Diamond Light ...
