We consider lasing modes in the microcavity shaped as a circular active disk placed in the centre of a passive dielectric ring as solutions to 2-D linear eigenproblem for the Maxwell equations with exact boundary and radiation conditions. The gain is introduced into the cavity material within the active region via the "active" imaginary part of the refractive index, and the modal frequencies and threshold values of gain are Sought as the eigenvalues.
