Optical biosensors have attracted much attention for their excellent sensitivity, fast response and label-free detection capabilities. Despite these advantages, conventional surface plasmon resonance ...

Hollow atoms are special atoms with multiple missing electrons in their inner shells, while their outer shells are still ...

Scientists at ETH Zurich have developed a powerful method to look deep inside single-atom catalysts—materials where every ...

We achieve Fano-like resonances in an all-in-fiber structure embedded with an in-line Mach-Zehnder interferometer (MZI). A fiber Bragg grating is inserted into MZI's one arm to form a resonance, which ...
