Dispersion compensation over distances in excess of 500 km for 10-Gb/s systems using chirped fiber gratings

Third-Order Dispersion in Linearly Chirped Bragg Gratings and Its Compensation

“…The third-order dispersion produced a ripple in the delayed tail of a Gaussian pulse (because the cubic dispersion is positive), reduced the peak power of the principal lobe, and increased its Cubic Dispersion of LC-FBG and Compensation 371 width. For long fiber links, the second-order dispersion compensation is achieved cascading several LCBGs and nonlinearities of the fiber have to be considered [5]. To study how this affects the transmission quality, a train of Gaussian pulses of width t 0 = 15 ps each and a bit time T bit = 75 ps (?…”

Dispersion compensation in directly modulated transmission system with the use of the half‐split‐band technique and chirped fiber grating

“…Furthermore, an additional expensive externally modulated transmitter, a fiber link, and an optical receiver are required for the latter. In recent studies, chirped fiber grating (CFG) used as a fiber dispersion compensation device in digital lightwave systems is a very attractive option for single-mode-fiber (SMF) transmission in high-speed long-distance systems [3]. However, its application in analog lightwave systems is not addressed.…”

“…By etching out beneath silicon, not only substrate loss but also parasitic capacitance is reduced, which improves the self-resonant frequency and quality factor significantly [2]. Thus, at low-gigahertz frequencies, metal loss is the main restriction of high-Q RF-MEMS spiral inductor design and should be carefully investigated [3].…”

Analysis of fiber Bragg grating with exponential–linear and parabolic taper profiles for dispersion slope compensation in optical fiber links

“…In particular, they can be efficiently used for dispersion compensation in high-speed longhaul optical communication systems [1][2][3], short-pulse generation and restoration [4,5]. Besides, FBGs can be used for the implementation of high-quality fiber laser cavities of various geometries [6,7] and semiconductor diode stabilization [8].…”
