“…However, because of the finite length of a real LCBG, its bandwidth is limited and both the magnitude and time-delay present ripples [11]- [13] and components of higher orders appear on the time-delay. The dominant higher order term on the time-delay varies with the square of the wavelength and its value depends on the grating parameters.…”

“…Large delay ripple amplitude can cause intersymbol interference resulting in a system eyeopening penalty, 4 whereas the delay ripple period, when it is large compared with the signal bandwidth, can result in device dispersion that varies with wavelength. 4,5 Several apodization techniques have been developed that are dynamic in nature, such as double-UV exposure 2,6 and phase-mask dithering, 7 or are static, such as variable-diffraction-efficiency phase masks. 8 These techniques ensure that the total average UV exposure along the length of the FBG device is kept constant.…”

Experimental results of fiber Bragg gratings fabricated with halftone amplitude transmission masks and 10-cm-long phase masks are presented for the first time to our knowledge. The performance of the devices is evaluated in terms of their spectral characteristics and deviation from linear group delay. Good out-of-band sidelobe suppression of -27 dB and group-delay ripple of ?9.5 ps is achieved for fully apodized grating devices.

“…In practice, however, there are delay ripples that can impact system performance. The ripples arise from imperfect apodization [1], phase errors in electron-beam fabricated phase masks [4], and nonuniformity of the fiber and UV irradiation [5], [6]. Large delay ripple amplitude can cause intersymbol interference resulting in a system eye-opening penalty [5] while the delay ripple period, when it is large compared to the signal bandwidth, can result in device dispersion that varies with wavelength [3], [5].…”
