| Abstract(in English) | Optical burst systems and optical packet systems require optical sources capable of high-speed wavelength switching. Tunable distributed amplification (TDA-) DFB laser is developed as one of candidates. Although a high speeding control with linear model realized a wavelength switching time of 60 ns, a further high-speed switching is required in a future optical switching system. We developed a nonlinear model to reduce modeling error and performed feedforward control. This realized a wavelength switching time of 22 ns, which is about one third of conventional one. |
