<P>PROBLEM TO BE SOLVED: To solve the problem wherein a conventional dispersion compensator cannot flexibly cope with a request from a transmission system, because the dispersion compensator is large in size and has large optical loss and a fixed dispersion compensated amount. <P>SOLUTION: A compensator for light wavelength dispersion has a dispersive medium 4, whose front and rear faces are parallel and which has a function for generating group delay wavelength dispersion of an optical pulse, and a mirror 5 for reflecting light, wherein an optical beam 3, immediately before reaching the mirror, is perpendicular to the front face of the mirror 5 so that incident light and reflected light passes through the same route. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
