Chirped moire fiber gratings operating on two-wavelength channels for use as dual-channel dispersion compensators

摘要

Long continuously chirped moire fiber gratings are demonstrated. Clean, dual-channel operation with dispersion equivalent to 100 and 200 km of standard fiber is shown from gratings of lengths 35.1 cm and 1 m. The gratings show reflection and time-delay characteristics of the same high quality as previously reported in single-channel chirped gratings.
