Determination of bandwidth and free spectral range for the silicon based ring resonators and racetrack microcavity resonators

摘要

This paper determines the free spectral range, FSR, and the half-power bandwidth, HPBW, of the racetrack microresonator, RTM, against the ring microresonator, RM, on silicon substrate. The accurate numerical FDTD has been used to calculate its characteris
