Abstract
We experimentally demonstrated the fabrication and the fundamental lasing evaluation of a microdisk
cavity by focusing on a fluorinated spherical polymer (FZ-001) to achieve a microdisk with small
absorption loss in the visible range. In a translucency evaluation, FZ-001, which is a host material
polymer of the microdisk, shows translucency over about 250 nm on the short wavelength. Transparency
on the longer wavelength region over about 320 nm is 99% or more. The polymer concentration of the
ink was set as high as 20 wt.%, and sufficient ejection was possible. In the WGM lasing evaluation, we
observed a comb-shaped spectrum with a peak near the fluorescence peak wavelength of doped dye
pyrromethene 597, and the obtained longitudinal mode spacing of 1.090 nm almost matched the
theoretical spacing. For the first time, we achieved ink-jet printing and lasing of the microdisk cavity by
FZ-001, a fluorine-based polymer.
