We report on MgF2 optical whispering gallery mode resonators, intended to operate in an optoelectronic microwave oscillator. We describe the definition of the physical and geometrical properties of the disk shape resonator, the fabrication process, and finally the mechanical and optical characterization obtained with the first fabricated devices. For the MgF2 disk, an optical quality factor of Q = 3.2 × 10^8 was measured at the telecoms wavelength lambda = 1.55 μm, and with a coupling performed through a tapered fiber.
