Abstract:
1. A tunable dispersion compensator for the compensation of chromatic dispersion in a light signal, said compensator comprising: a plurality of waveguide segments, each provided with an optical structure having a characteristic chromatic dispersion profile; an optical coupling arrangement having an input port for receiving said light signal, a plurality of input/output ports each coupled to a corresponding one of said plurality of waveguide segments for propagating the light signal therein and receiving the light signal therefrom after reflection by the optical structure of said corresponding waveguide segment, and an output port for outputting the light signal after successive reflection by each of said optical structures, said light signal thereby accumulating the characteristic chromatic dispersion profile of each of said optical structures; and a dispersion tuning device coupled to the plurality of waveguide segments for jointly tuning the characteristic chromatic dispersion profile of said optical structures, said device applying a same tuning force to each of said optical structures.
