Fibre optics is now the fastest and most reliable technology to deliver internet connection. Data is transmitted through fast-travelling pulses of light that bounce off the walls of the fibre cables ...

As the demand for bandwidth and high-speed transport grows, so does the use of fiber-optic based transport. One of the enabling technologies associated with optical transport are Fiber Bragg gratings ...

FAST spectrographs for studying weak light sources, such as the airglow and the aurora, commonly use cameras of large aperture and short focal length—5 in. and 4 in. respectively in a typical case. A ...
