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)(More)
We propose and demonstrate a reciprocating optical modulator having a phase-shifted fiber Bragg grating, a tunable fiber Bragg grating, and a resonant-type optical modulator. It enables effective(More)
