Dispersion compensation modules with fiber bragg gratings |
摘要 |
A device used for dispersion compensation of a plurality of optical signals passing through an optical transmission line. The device includes a photosensitive optical fiber including a long length, chirped Bragg grating providing dispersion compensation over a wide bandwidth of optical signals. The long length chirped Bragg grating has a reflection bandwidth greater than about 25 nm, and further has reduced distortion at a bit rate of about 10<-9>. This reduced distortion leads to a power penalty of less than 3 dB during less than 25 nm stepwise changes in wavelength of the plurality of optical signals across the wide bandwidth. The device provides a dispersion greater than about 100 ps/nm in a optical transmission line operating at 10 Gbit/s.
