Experimental Comparison of Optical Loss between the Silicon-on-Insulator Waveguide Corner Mirrors and Curves

Based on our previous work in modeling and numerical simulations that shows the transfer efficiency of a silicon-on-insulator (SOI) waveguide corner mirror (WCM) structure can achieve 95%, this paper experimentally demonstrates the optical loss advantage of SOI WCMs over waveguide curves. Both the numerical simulations and FDTD simulations further confirm the sustainable results of more than 94% and then the manufactured devices give a 0.30dB average optical loss in experiments. In contrary, the testing results of waveguide curves show that the optical propagation loss rates of 30 and 10dB/cm require the bending radii to be 0.5 and 2.0mm, respectively.

基于我们以前在建模和数值模拟方面的工作，该工作显示了硅启用器（SOI）波导角镜（WCM）结构的转移效率可以达到95％，本文在实验上证明了SOI WCM的光损失优势超过了波导。曲线。数值模拟和FDTD模拟都进一步证实了94％以上的可持续结果，然后制造的设备在实验中给出了0.30dB的平均光损失。相反，波导曲线的测试结果表明，光学传播损耗率为30和10dB/cm，弯曲半径分别为0.5和2.0mm。
