| Outline of Final Research Achievements |
A microcavity can confine light in a tiny space. We build coupled optical resonator system to demonstrate various functional operations. First, we constructed a coupled system using ultrahigh-Q silica toroid microcavities, and demonstrated photonic memories with 20-ns trapping time, or Brillouin lasing having high frequency accuracy.
Next we tried to couple photonic crystals with tapered nanofiber and demonstrated dynamic formation of resonators. In addition, we achieved very high coupling of light to an optical fiber by using this setup.
Finally, we demonstrated the coupling between silica toroid microcavity with photonic crystal slab.
