Tunable dispersion slope compensator with a chirped fiber grating and a divided thin-film heater for 160-Gb/s RZ transmissions

摘要

We have developed the tunable dispersion slope compensator with a chirped fiber grating and a divided thin-film heater composed of 32 thin-film heaters for single-channel 160-Gb/s return-to-zero (RZ) transmission. We successfully demonstrated the dispersion slope change between -20 and +20 psm/sup 2/ and ability of this dispersion slope compensation in 160-Gb/s RZ transmission by the simulations.
