MMI-MZI级联型1×8热光开关模拟及验证数据集

围绕国家信息领域中高端光电子芯片与器件国产化等国家战略性需求，开展光开关的研究，一个二氧化硅波导 1 × 8 热光开关，由级联三级马赫-曾德尔干涉仪组成（MZIs） 进行演示。MMI-MZI 1 × 2 开关单元采用多模干扰 （MMI） 耦合器由于其对波长不敏感和良好的制造耐受性。光束传播方法 （BPM） 为用于开关设计和优化。在准备过程中采用了标准 CMOS 技术的开关结构。在 1550 nm 处，1 × 8 开关的测量结果表明，光纤到光纤的插入损耗对于所有路由状态，范围为 3.4 到 3.6 dB。同时，消光比不小于 15.63 dB，并且串扰被限制在低于 − 15.65 dB 的范围内。由于采用马赫-曾德尔调制器结构，平均驱动功率通道切换为 315.8 mW。在 1500 至 1620 nm 的波长范围内，消光比大于 15.06 dB，插入损耗小于 5.8 dB，并且所有路由状态的 PDL 都小于 1.18 dB。实验结果与仿真结果吻合较好，证明了所提出的开关在宽带下具有良好的电位应用。To address national strategic demands including the localization of high-end optoelectronic chips and devices in the information domain, research on optical switches was carried out, and a silica waveguide 1×8 thermo-optic switch implemented with cascaded three-stage Mach-Zehnder interferometers (MZIs) was demonstrated. The MMI-MZI 1×2 switching unit utilizes multimode interference (MMI) couplers due to their wavelength-insensitive property and excellent manufacturing tolerance. The beam propagation method (BPM) was employed for the design and optimization of the switch. The switch was fabricated using standard CMOS technology during the manufacturing process. At 1550 nm, the measurement results of the 1×8 switch show that the fiber-to-fiber insertion loss ranges from 3.4 to 3.6 dB for all routing states. Meanwhile, the extinction ratio is no less than 15.63 dB, and the crosstalk is constrained to below −15.65 dB. Owing to the adoption of the Mach-Zehnder modulator structure, the average driving power for channel switching is 315.8 mW. Within the wavelength range of 1500 to 1620 nm, the extinction ratio exceeds 15.06 dB, the insertion loss is less than 5.8 dB, and the polarization-dependent loss (PDL) for all routing states is below 1.18 dB. The experimental results agree well with the simulation results, demonstrating that the proposed switch has promising potential applications in broadband scenarios.
