Nature is filled with remarkable visual phenomena created by microscopic surface structures that interact with light in ...

Scientists have hypothesized for over six decades the possibility of observing a form of wave reflections known as temporal, or time, reflections. Researchers detail a breakthrough experiment in which ...

Using the trapped rainbow effect to slow down or even stop light has been widely studied. However, high loss and energy leakage severely limited the development of rainbow devices. Here, we observed ...

Chemical processes can be monitored using various optical fiber-based probes in normal-incidence reflection or surface-reflection configurations 1,2. A major advantage of such probes is their ...
