Outline of Final Research Achievements	We studied the nonlinear dynamics of mechanical resonators to find new physical phenomena and to develop novel-concept mechanical devices. We demonstrated new phonon dynamics, such like phonon lasing, parametric frequency conversion, and dynamic phononic crystal waveguide. The phonon lasing operation generates very clean mechanical oscillation using the similar principle as optical lasers. The parametric frequency conversion enables rapid transfer of mechanical oscillation between different mechanical modes, allowing the fast annihilation of mechanical vibrations. The dynamic phononic crystal waveguide makes it possible to switch the propagation of sound waves with electrical signals. We also demonstrated 2-mode squeezing, which can be applied to study quantum mechanical behavior of phonons in future. These results provide the possibility to use the mechanical resonators, which was so far used only as passive devices, as more important active devices in future.
