Abstract

This paper proposes the simulations of racetrack microcavity resonator on a silicon substrate. The FDTD simulation was used as a numerical tool to find the optimized dimensions of the structure for 1.55μm wavelength. A simple modeling based on mode coupling theory was also proposed to find the spectral characteristics of the device. That is the device obtains the characteristics: FSR of 21.5 and Q of 155 from mode coupling theory, compared with the characteristics: FSR of 22 and Q of 135 from FDTD method. This means the proposed analytic model of mode coupling theory could be employed for the method to promptly characterize the device, as well as the other structures.
