CHROMATIC DISPERSION COMPENSATOR

摘要

The present invention is a chromatic dispersion compensator. The chromatic dispersion compensator includes a first 3-port optical circulator, a first grating coupled to the second optical port of the first 3-port optical circulator. A polarization controller is coupled to the third optical port of the first 3-port optical circulator. The chromatic dispersion compensator further includes a second 3-port optical circulator, the polarization controller is coupled to the first optical port of the second 3-port optical circulator and a second grating is coupled to the second optical port of the second 3-port optical circulator.
