Through numerical modeling, we study routing of the light pulses in coupled cylindrical whispering gallery mode microresonators. The coupling of light in and out of such structures is provided using strip-waveguides. We show that such photonic molecules display a complicated resonant behavior, leading to a nonreciprocal transport and a wavelength-dependent connectivity of the optical ports.
Photonic molecules formed by microresonators with coupled whispering gallery modes were studied by finite-difference time-domain modeling. Mode splitting was observed due to coherent coupling. Spatial mode distribution was shown to be different for each coupled mode. The advantages of photonic molecules over single resonators for sensing applications were demonstrated.
Clusters of circular resonators with coupled whispering gallery modes (WGMs) have interesting spectral and optical transport properties. We employ the finite-difference time-domain method to numerically study these properties. Using evanescent couplers, we show that various configurations of cavities display distinct spectral features (mode splitting) in the vicinity of their WGMs resonances. These...
