We studied the interaction of a two-level atom with a frequency modulated cavity mode in an ideal optical cavity. The system, described by a Jaynes-Cumming Hamiltonian, gave rise to a set of stiff nonlinear first order equations solved numerically using implicit and semi-implicit numerical algorithms. We explored the evolution of the atomic system using nonlinear dynamics tools, like time series, phase plane, power spectral density, and Poincar\'{e} sections plots, for monochromatic and bichromatic modulations of the cavity field. The system showed quasiperiodic and possibly chaotic behavior when the selected monochromatic frequencies, or ratio of the bichromatic frequencies were irrational (incommensurate) numbers. In addition, when the modulated frequencies were overtones of the Rabi frequency of the system, a single dominant frequency emerged for the system.
