| Research Abstract |
New millimeter-wave/terahertz-wave signal generation devices utilizing nonlinear optical difference frequency generation (DFG) in a rectangular waveguide resonator were studied in detail. By using detailed analyses based-on the coupled-mode theory and the finite-domain time-domain (FDTD) method, basic device operations were identified and a proto-type device operating in the 60GHz-band was designed. In the experiment, 60GHz signal generation was successfully demonstrated in the fabricated device using LiTaO3 crystal. The measured frequency response of the generated DFG signal was in good agreement with the theoretical one. In addition, the applications of the DFG technique to optical cross-/auto-correlation devices were also proposed and expected characteristics were shown theoretically. The fusion with standard rectangular waveguide circuits and higher frequency signal generation in the terahertz ranges were also discussed.
