Abstract

We present a mode converter in the silicon-on-insulator platform, which enables highly efficient, broadband coupling between a strip waveguide and a strip-loaded slot waveguide near 1.55 μm. The proposed converter has the benefit of electrically isolating the two arms of the slot waveguide. We fabricated and tested our mode converters, and achieved 0.81 ±0.49 dB per converter insertion loss in the best set of devices, in agreement with simulation.
