“…In practice, sampled gratings have been in continuous development since 1995 [94][95][96][97][98][99], with only recent reports of devices providing dispersion compensation at 100 GHz spacing across the entire C-band from M. Morin et al from Teraxion [99]. The sampling process has, however, found application in transforming singlechannel tunable dispersion and slope compensators into few-channel compensators, as will be discussed in the next section.…”

“…Chirping the sampling period [in addition to the chirp in the underlying grating periodicity] can produce slope-matched dispersion that varies linearly with wavelength." Ibsen argued in 1994 [95] that "sampled gratings are more attractive than overwriting many gratings as different wavelength in that same length of fiber since exact wavelength matching [between] the channels is automatically achieved from the sampling process, and the grating writing time is minimized." However, precise alignment of the central frequencies of the comb of channels to the ITU grid is not automatically achieved.…”

“…Loh et al from E-TEK in 1999 proposed using the blank regions in the grating produced by the sampling process to interleave multiple sampled gratings within the same fiber as an alternative design approach to the large optical index changes required to realize a reasonable number of channels from a single sampled grating [96]. [95], demonstrating a four-channel device from with uniform insertion loss and dispersion of −3200 ps/nm in a 4 × 10 Gbps WDM transmission experiment over 200 km of SMF with less than 1 dB Q-penalty compared to back-toback.…”

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.

“…It can be fabricated by only one phase mask and has the ability of multichannel dispersion compensation. Simple binary sampling function [4], sinc-sampling function [5], and more complicated interleaved sampling functions [6] have been proposed. A 22.5-cm-long sinc-sampled CSBG dispersion compensator has been demonstrated on a 4 ‫ء‬ 10-Gb/s 200-km transmission line [7].…”

seen that the combined model performs much better than the traditional coupling model. The direction finding results corresponding to the different active element patterns are plotted in Figure 10. As expected, the combined model outperforms the traditional coupling model, as it can clearly distinguish the two incoming signals. CONCLUSIONSThis Letter has proposed a combined model to describe the response of an antenna array in the presence of both mutual coupling and platform effects. The mutual coupling between the array elements is described by a coupling matrix. In addition, the platform effect is approximated with the use of the point-scatterer model. An algorithm has been proposed based on matching pursuit to determine the model coefficients. Numerical results show that the active element patterns reconstructed from the model are in good agreement with the actual data. The main attractiveness of the new model is that it provides physical insights into the coupling and scattering mechanisms. By parametrizing the active element patterns with the use of the proposed model, one can locate the position and strength of the dominant point scatterers that give rise to platform scattering.

“…Inter-channel dispersion slope is where the different channels experience different amount of dispersion, this especially impacts on wavelength division multiplexing (WDM) systems and needs to be carefully considered when the bit rate is 10Gb/s or beyond. There are many schemes proposed to solve the inter-channel dispersion slope problem, such as multi-channel fiber Bragg gratings (FBGs) [1,2], ring resonators [3], and Gires-Tournois etalons [4,5]. Intra-channel dispersion slope is where the dispersion experienced by each wavelength component within an optical pulse is different, this distorts the signals within each channel.…”

We present a novel tunable dispersion compensator that can provide pure slope compensation. The approach uses two specially designed complex fiber Bragg gratings (FBGs) with reversely varied third-order group delay curves to generate the dispersion slope. The slope can be changed by adjusting the relative wavelength positions of the two FBGs. Several design examples of such complex gratings are presented and discussed. Experimentally, we achieve a dispersion slope tuning range of +/-650ps/nm 2 with >0.9nm usable bandwidth.
