Transmission of optical signals in today’s telecommunication system is facing lots of technical problems. The solution lies on a particular type of light wave known as optical soliton. These light pulses will be the perfect solution for transmitting signals and also digital data in communication systems. Soliton has the ability to travel over long distances without being distorted. Microring resonators are introduced as a filter. Microring could be performed as the device for security purposes. By varying the transmission coefficients from 0.25 to 0.75, ring radius from 5?m to 15?m, and coupling coefficients, ? from 0.25 to 0.85, the performance of the ring resonator is examined in terms of free spectral range (FSR), Full Width Half Maximum (FWHM), Finesse (F), Quality Factor (Q) and time-domain at output signal. The conditions and controls to have a better performance of microring resonator were studied. Results obtained showed that to obtain a higher FSR and lower FWHM with maximum transmission are by using the ring radius of 15?m, the transmission coefficient of 0.75 and with the coupling coefficient of 0.25. In conclusion, the results obtained showed that the performance of the microring resonator are governed by the transmission coefficient, coupling coefficient, ring radius and time-domain factor.
