Coupled microcircular resonators tangentially coupled to a bus waveguide, which is between the resonators, are numerically investigated by the finite-difference time-domain technique. For symmetrically coupled microcircular resonators with refractive index of 3.2, radius of 2 μm , and width of the bus waveguide of 0.4 μm, a mode Q factor of the order of 10 5 is obtained for a mode at the frequency of 243 THz . An output coupling efficiency of as high as 0.99 is calculated for a mode with a Q factor ranging from 10 3 to 10 4 . The mode Q factor is 2 orders larger than that of the modes confined in a single circular resonator tangentially coupled to the same bus waveguide. Furthermore, the high Q traveling modes in the coupled microcircular resonators are suitable for optical single processing.
