We propose and numerically analyze a unique optical waveguide crossing based on a silicon-on-insulator (SOI) slab waveguide structure. The optical waveguide crossing consisting of four curved mirrors made of silica walls and beam spot-size converters formed in a silicon core layer of the SOI slab waveguide. Based on our design with a device footprint of 15 × 15 μm2, we obtained excellent device performances such as insertion loss of-0.3 dB, crosstalk of less than-35 dB in the wavelength range from 1.25 μm to 1.6 μm with the 3D-FDTD simulation.
