| Outline of Final Research Achievements |
Extension of optical fiber channel capacity is required for increase of data traffic in the Internet. For the purpose, the researcher proposed self-routing optical circuits by combination of multi-level signal amplitude and wavelength division multiplexing (WDM) systems. The circuits include nonlinear refractive index to respond with high or low signal amplitude to show different amount of index change. As fundamental wave-guiding structure and optical circuit component, photonic crystal structure with periodicity is adopted to achieve smaller circuit size compared with conventional slab waveguide. The design parameters are obtained by numerical computation and experiment in microwave scaled model.
