Title:
APPARATUS AND METHOD FOR WAVELENGTH DIVISION MULTIPLEXING
Document Type and Number:
WIPO Patent Application WO2002046803
Kind Code:
A3
Abstract:
A dispersion mitigating interleaver assembly has a first unbalanced Mach-Zehnder interferometer (MZI) assembly which includes first and second output ports and which has first tranmission vs. wavelength curve and a first dispersion vs. wavelength curve. The dispersion mitigating interleaver assembly also includes a second unbalanced MZI assmbly which has a second transmission vs. wavelength curve and a second dispersion vs. wavelength curve. The second unbalanced MZI assembly receives an output from one of the first and second output ports of the first unbalanced MZI assembly. 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 rspect to the first dispersion vs. wavelength curve, such that dispersion is substantially cancelled by the cooperation of the first and second unbalanced MZI assemblies.
