We report the first observations of bifurcation routes to chaos in an all-optical resonator. Generation of associated deep and sustained Ikeda oscillation of the smooth CO 2 laser input pulses at twice the round-trip time of the Fabry-Perot resonator provides a high-frequency ( ca .0.1 GHz) passive optical modulator device. Results are in excellent agreement with our adaption of optical bistability theory to the time-dependent regime
