“…With coresonance of two orthogonal WGMs of very different quality factors (Qs), light of one polarization is input, and the throughput of the same polarization is detected. 8 Using frequency-scanned cw input, the throughput will show spectral features of CMIT or ATS (a peak within a dip), or of CMIA (a dip within a dip), depending *atr@okstate.edu; phone 1 405 744-6742; fax 1 405 744-6811; rosenberger.okstate.edu…”

Coresonant, but orthogonally polarized, whispering gallery modes can couple to each other via the optical spin-orbit interaction. This cross-polarization coupling (CPC) can result in coupled-mode-induced transparency, attenuation, or Autler-Townes splitting. By fitting observed throughput spectra to a numerical model, the CPC strength can be determined and found to agree with the theory. The throughput response to input amplitude modulation provides an independent method of measuring the CPC strength. Observation and fitting of throughput spectra of both polarizations confirms that CPC is nonreciprocal. Induced transparency and attenuation can be observed even without CPC, by utilizing mode superposition. All these effects will be reviewed.

Coupling of light from a microresonator TE mode to a coresonant TM mode will have a different strength than that of coupling from the TM mode to the TE mode. This coupling nonreciprocity, deriving from the optical spin-orbit interaction, is modeled numerically and confirmed experimentally by observing coupled-mode induced transparency and Autler-Townes splitting. By measuring the throughput spectrum in both polarizations when the input directly excites modes of only one polarization, the coupling strengths in both directions can be determined simultaneously by fitting to the numerical model. Some examples and implications are discussed here.

We explore the nonlinear interactions of an optomechanical microresonator driven by two external optical signals. Optical whispering-gallery waves are coupled to acoustic surface waves of a fused silica medium in the equatorial plane of a generic microresonator. The system exhibits coexisting attractors whose behaviors include limit cycles, steady states, tori, quasi-chaos, and fully developed chaos with ghost orbits of a known attractor. Bifurcation diagrams demonstrate the existence of self-similarity, periodic windows, and coexisting attractors and show high-density lines within chaos that suggests a potential ghost orbit. In addition, the Lyapunov spectral components as a function of control parameter illuminate the dynamic nature of attractors and periodic windows with symmetric and asymmetric formations, their domains of existence, their bifurcations, and other nonlinear effects. We show that the power-shift method can access accurately and efficiently attractors in the optomechanical system as it does in other nonlinear systems. To test whether the ghost orbit is the link between two attractors interrupted by chaos, we examine the elements of the bifurcation diagrams as a function of control parameter. We also use detuning as a second control parameter to avoid the chaotic region and clarify that the two attractors are one.
