Broadband tunable dispersion compensator |
摘要 |
<p>A long variable pitch Bragg grating is written in an optical fiber (10) in which wavelength division multiplexed transmission channels propagate. A pair of heating systems (20) are distributed over the grating and are controlled independently to compensate simultaneously the chromatic dispersion on several transmission channels.</p> |
