ABSTRACT:
The present invention is a device for adding delay and compensating for dispersion in an optical signal. In a first embodiment, the present invention is made up of a waveguide, preferably an optical fiber, having two or more forward-reflecting gratings for separating an optical signal into user-selected wavelength portions to be propagated in different propagation modes and then recombining them to achieve the desired result. In another embodiment, the present invention is a waveguide, preferably an optical fiber, having three or more gratings where the gratings may be forward-diffracting or backward-reflecting for extending the capability of the first embodiment.
