A semiconductor-based tunable optical dispersion compensation method and apparatus
for multiple channels. In one aspect of the present invention, an apparatus according
to an embodiment of the present invention includes a semiconductor material. An
optical path through the semiconductor material is included. The optical path is
optically coupled to receive an optical beam. A nonlinearly chirped Bragg grating
is disposed in the semiconductor material. The optical path includes the nonlinearly
chirped Bragg grating to substantially reduce chromatic dispersion in the optical beam.
