A short length of optical fiber that filters out a particular wavelength. Periodically spaced zones in the fiber core are altered to have different refractive indexes slightly higher than the core.
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 ...
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 ...
