Circular Economy has been officially included in the Emerging Sources Citation Index (ESCI) by Web of Science, a leading global provider of scientific and scholarly research information.
While fiber Bragg grating is widely used for selectively filtering wavelengths during optical transmission, existing techniques are unsuitable for bandwidth filtering of broadband optical signals. Researchers have now demonstrated that chirped and tilted fiber Bragg grating (CTFBG) using femtosecond laser line-by-line technology can facilitate highly specific and versatile bandwidth filtering in broadband signals. The technique may offer several added advantages in optical signal filtering beyond flexibility and customizability.
