High-performance 40 Gbit/s fibre Bragg grating tunable dispersion compensator fabricated using group delay ripple correction technique

摘要

A recently proposed UV correction method is used to reduce group delay ripple in a chirped fibre grating tunable dispersion compensator. In 43 Gbit/s CSRZ system tests, the corrected grating had less than 0.5 dB OSNR penalty over the tunable dispersion range of 270 to 750 psm.
