| Outline of Final Research Achievements |
To realize a high-accuracy wavelength laser for the Flexible-Grid Network, we proposed a novel method of detecting wavelength deviation from reference wavelengths by using a microwave band-pass filter and constructed the control system. The experimental results showed a wavelength accuracy within 0.01 GHz which meets a requirement at the optical communication system. For a future optical packet network, we also studied a fast wavelength switching at a laser. Our devised current controller based on the transfer function of the laser reduced the wavelength switching time down to 60 ns. As for the outputs, the number of the published article has been four as well as twenty-nine presentations.
