| Outline of Final Research Achievements |
Utilizing meta-material structures operating in microwave to THz-wave ranges, new high-speed optical modulation devices for converting wireless signals to optical signals are analyzed, designed and fabricated. For the fabrication of the designed device, z-cut LiNbO3 was used as a substrate. The optical waveguides, metal patterns and three-dimensional structures were fabricated by use of the annealed-proton-exchange method, the lift-off technique with vapor film depositions, and substrate bonding with a UV adhesive, respectively.
The fabricated modulation devices were tested by use of a laser beam with a 1550-nm wavelength and wireless signals. As a result, clear optical modulation sidebands were observed and the basic performances were verified successfully.
