The diameter self-regulation of optical fibre tapers produced using a CO2 laser has been examined theoretically and modelled numerically. Results of the simulation show that for small diameters, where the geometric model of absorption cannot be used, the Mie theory of absorption derived from the Maxwell equations exhibits structure due to resonances of the CO2 laser radiation in the tapered fibre. At small diameters, the polarisation state of the CO2 laser is important, and resonance effects cause the equilibrium temperature/diameter graph to exhibit oscillations.
