Tunable wideband dispersion compensator |
摘要 |
A system for compensating chromatic dispersion includes a long variable pitch Bragg grating written in an optical fiber in which wavelength division multiplexed transmission channels propagate. A system for generating a thermal gradient includes at least two heating systems distributed over the grating and controlled independently of each other to compensate simultaneously the chromatic dispersion on a plurality of transmission channels.
