ObjectiveThe silicon-based micro ring resonator modulator is the core component of optical interconnect in ultra short distance transmission chips and an important device in applications such as quantum computing. Its modulation efficiency is generally around 1.88 V·cm, and the modulation rate can reach 50 Gbps. However, its modulation efficiency and modulation rate are significantly affected by temperature changes. Efficient control and stabilization of its modulation efficiency are of great value in improving its optical interconnect performance.MethodsIn this work, we propose an enhanced random sampling method, termed T-RANSCAC, to stabilize the efficiency of silicon-based micro-ring resonator modulators. We extracted the experimental system for the silicon-based micro-ring resonator modulator and collected data on the resonant wavelength and operating temperature through experiments. This data was analyzed to develop a model curve for wavelength control. Based on this model, we established a wavelength control system for the silicon-based micro-ring resonator modulator, which was subsequently validated through experimental verification.Results and DiscussionsIn this paper, we analyze the experimental data of the resonant wavelength and operating temperature of the silicon-based micro-ring resonator modulator, revealing the relationship between these two variables. This relationship is pre-stored in the FLASH memory of the wavelength control system and is utilized by an algorithm that automatically compensates for wavelength variations. We observe the modulation efficiency over the long-term operation of the system following wavelength compensation. Without this compensation, the modulation efficiency deteriorates over time. However, when wavelength compensation is performed based on the established relationship curve, the system's bit error rate can be maintained within an optimal range.ConclusionsWe analyze the test data of the silicon-based micro-ring resonator modulator, demonstrating a linear relationship between the resonant wavelength and changes in operating temperature, along with empirical values. Building on this analysis, we develop a wavelength control system for the modulator that enables stable long-term operation. This system offers a practical control method for applications, enhancing the overall feasibility and usability of the silicon-based micro-ring resonator modulator. It can stabilize the bit error rate of communication systems based on silicon-based micro ring resonator modulators at 10⁻⁷ when the transmission rate is 45 Gbps.
