摘要：

The coupling mechanism of a system in which two identical microresonators with slot are coupled through a tapered fiber is theoretically investigated and its transmission rate is numerically calculated. Physical parameters are evaluated for their impacts on the transmission spectra. Fano-like lineshape is observed under certain condition (gamma(c) > 2 kappa) and optimization of dominant parameters (kappa(1)/kappa(0), kL, gamma(c)/kappa(0) and Q(0)) is applied to make the lineshape more steepened and sharper. This structure is promising for application in optical switch, sensing and research on Fano resonance.
