    摘要: In one embodiment, an waveguide includes a primary core configured to guide electromagnetic waves having relatively long wavelengths, a unit cell having a core configured to guide electromagnetic waves having relatively short wavelengths, the relatively long wavelengths being at least twice as long as the relatively short wavelengths, and a cladding material that surrounds the primary core and the unit cell.

    摘要: Systems and method of compensating for transmission impairment are disclosed. One such method comprises receiving a wavelength-division multiplexed optical signal. The received optical signal has been distorted in the physical domain by an optical transmission channel. The method further comprises propagating the distorted optical signal backward in the electronic domain in a corresponding virtual optical transmission channel. The backward propagation fully compensates for fiber dispersion, self-phase modulation, and cross-phase modulation (XPM) and partially compensates for four-wave mixing (FWM).
