Demonstration of 40-Gb/s Low-Group-Delay-Ripple Tunable Dispersion Compensator Using Angled Etalon With Multiple Reflections

We experimentally demonstrated a high-performance tunable dispersion compensator with a simple configuration using an angled etalon with multiple reflections. We developed a group-delay model of the compensator and designed to suppress the group-delay ripple (GDR). A tunable dispersion range of plusmn250ps/nm and a low <2.0-ps GDR were shown
