We propose and theoretically investigate the possibility of using spherical, whispering gallery mode microresonators based on germanosilicate glasses with different GeO2 contents for generating optical frequency combs in the dissipative soliton regime under pumping at a wavelength of 1.55 or 2 μm. The dispersion and nonlinearity of microspheres of different radii are calculated and analysed, and their optimal characteristics and the expected parameters of the output radiation are determined. It is shown that the spectral widths of optical frequency combs formed in 0.8SiO2 – 0.2GeO2 and GeO2 glass microspheres pumped at λ = 1.55 and 2 μm can be ~200 and ~300 nm, respectively. In these cases, in addition to the dissipative soliton with a duration of ~100 fs, the generation of dispersive waves is also observed.
