Chirped fiber bragg gratings
WebJul 1, 2024 · Firstly, we manufacture a CFBG with above chirped phase mask. Secondly, we replace the chirped phase mask by a common phase mask (length: 27 mm, period: 1073.7 nm) and use C + L ASE (1528−1602 nm) instead of 1060 nm ASE. At last, keep the fiber locked in the same position and launch the excimer laser again. WebA chirped FBG is a special type of FBG in which the period of the grating varies linearly along its length. The result is a wavelength selective filter where a broad range of …

WebApr 20, 2024 · In this work, a method is proposed and demonstrated for fabrication of chirped fiber Bragg gratings (CFBGs) in single-mode fiber by femtosecond laser point-by-point inscription. CFBGs with bandwidths from 2 to 12 nm and dispersion ranges from 14.2 to 85 ps/nm are designed and achieved.
WebThe potential of chirped fiber gratings for dispersion compensation was demon- strated during the 1990s in several transmission experiments [68]–[73]. In 1994, GVD compensation over 160 km of standard fiber at 10 and 20 Gb/s was realized [69]. In 1995, a 12-cm-long chirped grating was used to compensate GVD over 270 km of fiber at 10 Gb/s [70].
