Abstract

This paper proposes a design of the racetrack microcavity resonator based on silicon substrate. The optimised dimensions of the structure were found by FDTD simulation. The characteristics were also found by the method, and further compared with another model of mode coupling theory. The optimised dimensions of straight guide at wavelength 1.55$\mu\textrm{m}$ are thickness and width of 0.4 $\mu\textrm{m}$. The curve guide provides the maximum at 1 $\mu\textrm{m}$ whereas the resonating section require small coupling section of about 3 $\mu\textrm{m}$.
