Abstract. Intersection of two or more silicon slot waveguides is inevitable in modern optical integrated circuits based on a silicon-on-insulator platform. We design a Maxwell’s fisheye lens as the crossing medium for three Si slot waveguides and numerically investigate its characteristics, such as insertion loss, cross talk, and bandwidth. For the 3  ×  3 slot waveguide crossing, the average insertion loss of 1.2 dB and cross talk levels lower than −15.1  dB are achieved in an ultrawideband…
