We have developed a technique for realizing a two-dimensional quadrupolarmicrocavity with its deformation variable from 0% to 20% continuously. Weemployed a microjet ejected from a noncircular orifice in order to generate astationary column with modulated quadrupolar deformation in its cross section.Wavelength red shifts of low-order cavity modes due to shape deformation weremeasured and were found to be in good agreement with the wave calculation forthe same deformation, indicating the observed deformation is quadrupolar innature.Comment: 7 pages, 6 figures, intended for Rev. Sci. Instu
