Abstract:
A dispersion mitigating interleaver comprising:a first unbalanced Mach-Zehnder interferometer assembly having first and second output ports and having a first transmission vs. wavelength curve and a first dispersion vs. wavelength curve; a second unbalanced Mach-Zehnder interferometer assembly having a second transmission vs. wavelength curve and a second dispersion vs. wavelength curve, the second unbalanced Mach-Zehnder interferometer assembly receiving an output from one of the first and second output ports of the first unbalanced Mach-Zehnder interferometer assembly; and wherein the second transmission vs. wavelength curve is substantially the same as the first transmission vs. wavelength curve and the second dispersion vs. wavelength curve is substantially opposite with respect to the first dispersion vs. wavelength curve, such that dispersion is substantially cancelled by the cooperation of the first and second unbalanced Mach-Zehnder interferometer assemblies.
