Query: Monolithic integration of a high-quality factor lithium niobate
  microresonator with a free-standing membrane waveguide using femtosecond
  laser assisted ion beam writing (FLAIBW)   We demonstrate integrating a high quality factor lithium niobate microdisk
resonator with a free-standing membrane waveguide. Our technique is based on
femtosecond laser direct writing which produces the pre-structure, followed by
focused ion beam milling which reduces the surface roughness of sidewall of the
fabricated structure to nanometer scale. Efficient light coupling between the
integrated waveguide and microdisk was achieved, and the quality factor of the
microresonator was measured as high as 1.67*10^5.
