Outline of Final Research Achievements

In order to realize low-power consumption polymer three-dimensional (3D) switching circuits and develop related polymer functional devices, first we solved the issues of cracking due to multi-layer stacking of different kinds of polymers and deformation of waveguide shapes by optimizing the fabrication process. On the basis of these results, 4x4 configuration 3D optical switches were realized. Operation with rather low-power consumption, almost polarization independence and wide-wavelength range of 1530 to 1610nm was experimentally realized, showing the possibility to effectiveness of polymer waveguides to low-power consumption 3D optical switching circuits. At the same time, as the extension of polymer waveguide technologies to functional optical devices, an optical ring-resonator filter integrated with semiconductor optical devices and a waveguide-type Kretschmann surface plasmon resonant sensor were realized and clarified the wide effectiveness of polymer waveguide devices.
