摘要： The invention relates to a method for delaying a signal in the form of a light pulse or a pulse packet, wherein the signal for splitting up the frequency components is first of all exposed to an element having a strong chromatic dispersion, wherein at least individual frequency components of the split signal are subjected to a modulation and wherein, in order to compensate the dispersion generated, the signal thus processed is exposed to an element having a corresponding dispersion with a reverse sign.

摘要： A time compensation architecture for use with a plurality of optical signals is disclosed. It comprises means for receiving the plurality of optical signals, optical means for selectively delaying the propagation of each of the plurality of optical signals, and means for outputting the time delayed optical signals. The delay may be achieved by changing the indices of refraction or the material lengths of the elements and can either be an active or a passive compensation technique.

摘要： An apparatus and method are provided for filtering an optical signal by wavelength. An initially polarised signal is passed through a DGD element effective to alter the polarisation state of the components of the signal according to wavelength. A polarisation filter (polariser) is then provided to attenuate light having given polarisation states from the signal, thereby attenuating the wavelengths associated with said polarisation states. The invention finds particularly utility in the domain of vestigial sideband filtering, allowing the bandwidth of signals within a wavelength division multiplexed system to be reduced without introducing the deleterious effects associated with conventional wavelength filters.
