Optical dispersion compensator suitable for use with non-wavelength-locked transmitters

A compact and simple silica-waveguide 10-Gb/s tunable optical dispersion compensator (ODC) that works with uncontrolled wavelength transmitters by tracking the signal wavelength is demonstrated. Transmissions at 10.7 Gb/s over 5100 ps/nm of dispersion with a duobinary signal using a single pass of the ODC and 3825 ps/nm of dispersion with an unchirped non-return-to-zero signal using a double pass of the ODC are shown.
