A method to manufacture optical microfiber coil resonators embedded in Teflon has been demonstrated for what is the first time to the best of our knowledge. The resonator was obtained by wrapping a microfiber on a low refractive index rod and coating it with a Teflon resin. The coating process is investigated and discussed. Resonances in excess of 9 dB, a free spectral range of approximately 0.8 nm, and Q factors greater than 6000 have been observed in the embedded resonator. The device is compact, robust, and portable.
