ABSTRACT:
The present invention is directed towards systems and methods for adjusting intensity, wavelength and higher and lower frequency components of an optical signal. Photonic apparatus receives a first and a second optical signal. A waveguide provides an anomalous group velocity dispersion the first optical signal or the second optical signal and adjusts intensity or wavelength of the first optical signal or the second optical signal, in response to the anomalous group velocity dispersion. In some embodiments photonic apparatus receives an optical signal comprising a lower frequency component received an amount of time prior to a higher frequency component of the optical signal. A waveguide provides an anomalous group velocity dispersion for the optical signal and adjusts the amount of time between the higher frequency component and the lower frequency component in response to the anomalous group velocity dispersion.
