    This paper determines the possibly maximum rate for the optical signal transmitting thorough the racetrack resonator devices. The method of finite-difference time-domain was employed to determine how an optical impulse getting through the device. We observe that the signal requires a certain number of round-trips to couple the signal to the throughput, and causes the delay of the pulse outputting from the device. This indicates that the possible pulse width is in a range of picoseconds, which corresponding to the maximum transmission rate of over a hundred gigabits per second. © 2005 IEEE.

    This paper determines the maximum free spectral range (FSR) and the minimum half power bandwidth (HPBW) of the ring and racetrack resonators based on silicon substrate using FDTD. At the optimum cross-section that provides the compromised efficiency, the relationships between HPB W against the coupling efficiency and FSR, against the racetrack round trip have been obtained. The relationships would be utilized to determine the possibly maximum FSR of 60nm and the minimum HPBW of 5nm, or highest quality factor for the ring microresonator with 1μm radius. © 2005 IEEE.
