“…to obtain a defined scope of group delay [9,10]. Chirped [11], non-linear chirped [12], apodized [13] or sampled [14,15] Bragg gratings are most commonly used in the case of dispersion compensators.The influence of the grating parameters on its third-order dispersion value have also been studied [16]. In some cases the acoustic effect allows control of the dispersion using a uniform FBG [17].…”

The article presents a tunable fibre optic dispersion compensator system, consisting of a specially designed cantilever beam and a uniform Bragg grating. It analyses the group delay and dispersion characteristics in the case that there is no apodization of the grating and also for a grating with apodization used for modulation of the refractive index. Various apodization parameters were tested, along with their effects on the dispersion characteristics of the entire system properties. It is demonstrated in the paper that the apodization parameter affects the compensator’s group delay characteristic. The finite elements method was used to design a compensator of such a shape that enabled chirp to be induced in a grating of a specified shape. A new design is presented for the system, in which the dispersion properties are tuned by the maximum value of the heterogeneous deformation of the compensator. The paper also includes results showing the effect of the maximum value of heterogeneous stress of the grating on the dispersion characteristics of the proposed construction.

“…Chollet and Goedgebuer [14] presented the experimental preparation of a LiNbO 3 composed optical filter used for reducing sidelobes in the asymmetry mode. Kolpakov et al [15] used the same technique to produce a dispersion-less Fabry-Perot fiber cavity with the use of a pair of fiber Bragg gratings. Applebuam and Chapman [16] developed a widely used technique in antenna arrays for sidelobe cancelling.…”

The simultaneous suppression of sidelobes and the sharpening of the central peak in the process of diffraction pattern detection based on asymmetric apodization have been investigated. Asymmetric apodization is applied to a semicircular array of two-dimensional (2D) aperture functions, which is a series of 'coded-phase arrays of semicircular rings randomly distributed over the central circular region of a pupil function' and is similar to that used in the field of diffractive optics. The point spread function (PSF) of an imaging system with asymmetric apodization of the discrete type has been found to possess a good side with suppressed sidelobes, whereas its bad side contains enhanced sidelobes. Further, the diffracted field characteristics are obtained in the presence of these aperture functions. Asymmetric apodization is helpful in improving the performance of the optical gratings or 2D arrays used in real-time imaging techniques.
