“…In 2002, Painchaud et al of Teraxion used a superposition approach to fabricate a dispersion compensator that operated over 32 WDM channels spaced at 100 GHz, for a total operation bandwidth of 25 nm [90]. The dispersion of the grating for each channel was adjusted on a per-channel basis to provide dispersion slope compensation.…”

Chromatic dispersion compensation is an integral part of WDM transmission system design. Compensator properties such as insertion loss, dispersion slope and effective mode area have a large impact on WDM system performance due to nonlinear optical propagation effects. Dispersion compensator imperfections, such as multi-path interference, group delay ripple, insertion loss ripple and limited per-channel compensation bandwidth, place additional limitations on the achievable transmission distance and capacity. In this paper, a survey of key WDM transmission system experiments is undertaken to 1) review the development of chromatic dispersion compensation technologies, 2) discuss the device characteristics that most impact system design for each technology, and 3) hopefully enable the reader to better evaluate compensator technologies for specific applications.

“…For examples, realization of chirped sampled FBGs (CSFBGs) with both comb-like filtering function and dispersion compensation functions are hard due to the imbalance of many parameters. There have been methods such as precise phase control using complicated holographic setup 6) or superposition of chirped gratings on the same sections of fibers, 7) however the gratings can not be realized with densed channel spacing and suffer from low reflectivity.…”

We introduce fabrication methods using phase-masks for spectral broadening and densification of sampled fiber Bragg gratings (FBGs), as well as enabling the in-channel dispersion compensability for future wavelength division multiplexing (WDM) systems. In channel dispersion compensation is obtained by maintaining the balance of grating parameters based on the calculations, the reflection bandwidth is broadened by interleaving different sampled FBGs and channel spacing is densified by using multiple phase shift method.
