Abstract

An optical pulse delay generator is provided. The optical pulse delay generator includes a first optical converter which is dispersive and separates the spectral components of the incoming optical pulse in a time domain. The first optical converter generating a converted optical signal. The optical pulse delay generator also includes a modulator to modulate the converted optical signal and to generate a modulated optical signal and a second optical converter connected to the modulator. The second optical converter being dispersive for overlaying the previously separated spectral components in the time domain and generating the delayed optical output pulse. The dispersion imposed by the second optical converter has the same amount of dispersion, but the opposite sign, as the first optical converter. At least one of the first and second optical converter includes at least two waveguide resonator rings which differ in their optical length.
