摘要

In recent years, on-chip multimode transmission has attracted great interest for its ability to expand link capacity on a single wavelength carrier. Waveguide crossing is an important building block for complex multiplexing systems. In this paper, we design and simulate a waveguide crossing structure based on the elliptical reflector which is suitable for the crossing of more than two guided modes. The simulated efficiencies of all three TE modes are better than 0.4 dB, and the crosstalk is around -40 dB in a wide spectral range. (C) 2019 Optical Society of America
