Dynamic chromatic dispersion control using coupled optical waveguides

摘要

According to an exemplary embodiment of the present invention, an apparatus for dynamically controlling chromatic dispersion in an optical signal includes a coupled waveguide structure, and a device which alters an index of refraction of the coupled waveguide structure to effect a change in the chromatic dispersion. According to another exemplary embodiment of the present invention, a method for dynamically controlling chromatic dispersion includes providing a coupled waveguide structure and selectively altering an index of refraction profile of coupled waveguide structure to effect a change in the chromatic dispersion in an optical signal.
