Compensation element for chromatic dispersion based on a photonic crystal; associated compensation system and method

摘要

Dispersion compensation system for an optical pulse propagated via an optical pulse transmission line, characterized by comprising: an optical pulse pickup unit provided on said optical pulse transmission line and picking up said optical pulse propagated via said optical pulse transmission line; a dispersion compensation unit provided on said optical pulse transmission line and giving chromatic dispersion to the optical pulse propagated via said optical pulse transmission line; and a control unit controlling the absolute value and the sign of chromatic dispersion given to said optical pulse by said dispersion compensation unit based on said optical pulse picked up by said optical pulse pickup unit.
