Abstract: 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.
